# ACCESS(5) ACCESS(5)
#
# NAME
# access - Postfix access table format
#
# SYNOPSIS
# postmap /etc/postfix/access
#
# postmap -q "string" /etc/postfix/access
#
# postmap -q - /etc/postfix/access <inputfile
#
# DESCRIPTION
# The optional access(5) table directs the Postfix SMTP
# server to selectively reject or accept mail. Access can be
# allowed or denied for specific host names, domain names,
# networks, host addresses or mail addresses.
#
# For an example, see the EXAMPLE section at the end of this
# manual page.
#
# Normally, the access(5) table is specified as a text file
# that serves as input to the postmap(1) command. The
# result, an indexed file in dbm or db format, is used for
# fast searching by the mail system. Execute the command
# "postmap /etc/postfix/access" in order to rebuild the
# indexed file after changing the access table.
#
# When the table is provided via other means such as NIS,
# LDAP or SQL, the same lookups are done as for ordinary
# indexed files.
#
# Alternatively, the table can be provided as a regular-
# expression map where patterns are given as regular expres-
# sions, or lookups can be directed to TCP-based server. In
# that case, the lookups are done in a slightly different
# way as described below under "REGULAR EXPRESSION TABLES"
# and "TCP-BASED TABLES".
#
# TABLE FORMAT
# The input format for the postmap(1) command is as follows:
#
# pattern action
# When pattern matches a mail address, domain or host
# address, perform the corresponding action.
#
# blank lines and comments
# Empty lines and whitespace-only lines are ignored,
# as are lines whose first non-whitespace character
# is a `#'.
#
# multi-line text
# A logical line starts with non-whitespace text. A
# line that starts with whitespace continues a logi-
# cal line.
#
# EMAIL ADDRESS PATTERNS
# With lookups from indexed files such as DB or DBM, or from
# networked tables such as NIS, LDAP or SQL, patterns are
# tried in the order as listed below:
#
# user@domain
# Matches the specified mail address.
#
# domain.tld
# Matches domain.tld as the domain part of an email
# address.
#
# The pattern domain.tld also matches subdomains, but
# only when the string smtpd_access_maps is listed in
# the Postfix parent_domain_matches_subdomains con-
# figuration setting (note that this is the default
# for some versions of Postfix). Otherwise, specify
# .domain.tld (note the initial dot) in order to
# match subdomains.
#
# user@ Matches all mail addresses with the specified user
# part.
#
# Note: lookup of the null sender address is not possible
# with some types of lookup table. By default, Postfix uses
# <> as the lookup key for such addresses. The value is
# specified with the smtpd_null_access_lookup_key parameter
# in the Postfix main.cf file.
#
# EMAIL ADDRESS EXTENSION
# When a mail address localpart contains the optional recip-
# ient delimiter (e.g., user+foo@domain), the lookup order
# becomes: user+foo@domain, user@domain, domain, user+foo@,
# and user@.
#
# HOST NAME/ADDRESS PATTERNS
# With lookups from indexed files such as DB or DBM, or from
# networked tables such as NIS, LDAP or SQL, the following
# lookup patterns are examined in the order as listed:
#
# domain.tld
# Matches domain.tld.
#
# The pattern domain.tld also matches subdomains, but
# only when the string smtpd_access_maps is listed in
# the Postfix parent_domain_matches_subdomains con-
# figuration setting. Otherwise, specify .domain.tld
# (note the initial dot) in order to match subdo-
# mains.
#
# net.work.addr.ess
#
# net.work.addr
#
# net.work
#
# net Matches the specified IPv4 host address or subnet-
# work. An IPv4 host address is a sequence of four
# decimal octets separated by ".".
#
# Subnetworks are matched by repeatedly truncating
# the last ".octet" from the remote IPv4 host address
# string until a match is found in the access table,
# or until further truncation is not possible.
#
# NOTE 1: The information in the access map should be
# in canonical form, with unnecessary null characters
# eliminated. Address information must not be
# enclosed with "[]" characters.
#
# NOTE 2: use the cidr lookup table type to specify
# network/netmask patterns. See cidr_table(5) for
# details.
#
# net:work:addr:ess
#
# net:work:addr
#
# net:work
#
# net Matches the specified IPv6 host address or subnet-
# work. An IPv6 host address is a sequence of three
# to eight hexadecimal octet pairs separated by ":".
#
# Subnetworks are matched by repeatedly truncating
# the last ":octetpair" from the remote IPv6 host
# address string until a match is found in the access
# table, or until further truncation is not possible.
#
# NOTE 1: the truncation and comparison are done with
# the string representation of the IPv6 host address.
# Thus, not all the ":" subnetworks will be tried.
#
# NOTE 2: The information in the access map should be
# in canonical form, with unnecessary null characters
# eliminated. Address information must not be
# enclosed with "[]" characters.
#
# NOTE 3: use the cidr lookup table type to specify
# network/netmask patterns. See cidr_table(5) for
# details.
#
# IPv6 support is available in Postfix 2.2 and later.
#
# ACCEPT ACTIONS
# OK Accept the address etc. that matches the pattern.
#
# all-numerical
# An all-numerical result is treated as OK. This for-
# mat is generated by address-based relay authoriza-
# tion schemes.
#
# REJECT ACTIONS
# 4NN text
#
# 5NN text
# Reject the address etc. that matches the pattern,
# and respond with the numerical three-digit code and
# text. 4NN means "try again later", while 5NN means
# "do not try again".
#
# REJECT optional text...
# Reject the address etc. that matches the pattern.
# Reply with $reject_code optional text... when the
# optional text is specified, otherwise reply with a
# generic error response message.
#
# DEFER_IF_REJECT optional text...
# Defer the request if some later restriction would
# result in a REJECT action. Reply with "450 optional
# text... when the optional text is specified, other-
# wise reply with a generic error response message.
#
# This feature is available in Postfix 2.1 and later.
#
# DEFER_IF_PERMIT optional text...
# Defer the request if some later restriction would
# result in a an explicit or implicit PERMIT action.
# Reply with "450 optional text... when the optional
# text is specified, otherwise reply with a generic
# error response message.
#
# This feature is available in Postfix 2.1 and later.
#
# OTHER ACTIONS
# restriction...
# Apply the named UCE restriction(s) (permit, reject,
# reject_unauth_destination, and so on).
#
# DISCARD optional text...
# Claim successful delivery and silently discard the
# message. Log the optional text if specified, oth-
# erwise log a generic message.
#
# Note: this action currently affects all recipients
# of the message.
#
# This feature is available in Postfix 2.0 and later.
#
# DUNNO Pretend that the lookup key was not found. This
# prevents Postfix from trying substrings of the
# lookup key (such as a subdomain name, or a network
# address subnetwork).
#
# This feature is available in Postfix 2.0 and later.
#
# FILTER transport:destination
# After the message is queued, send the entire mes-
# sage through the specified external content filter.
# The transport:destination syntax is described in
# the transport(5) manual page. More information
# about external content filters is in the Postfix
# FILTER_README file.
#
# Note: this action overrides the main.cf con-
# tent_filter setting, and currently affects all
# recipients of the message.
#
# This feature is available in Postfix 2.0 and later.
#
# HOLD optional text...
# Place the message on the hold queue, where it will
# sit until someone either deletes it or releases it
# for delivery. Log the optional text if specified,
# otherwise log a generic message.
#
# Mail that is placed on hold can be examined with
# the postcat(1) command, and can be destroyed or
# released with the postsuper(1) command.
#
# Note: use "postsuper -r" to release mail that was
# kept on hold for a significant fraction of $maxi-
# mal_queue_lifetime or $bounce_queue_lifetime, or
# longer.
#
# Note: this action currently affects all recipients
# of the message.
#
# This feature is available in Postfix 2.0 and later.
#
# PREPEND headername: headervalue
# Prepend the specified message header to the mes-
# sage. When this action is used multiple times, the
# first prepended header appears before the second
# etc. prepended header.
#
# Note: this action does not support multi-line mes-
# sage headers.
#
# Note: this action must be used before the message
# content is received; it cannot be used in
# smtpd_end_of_data_restrictions.
#
# This feature is available in Postfix 2.1 and later.
#
# REDIRECT user@domain
# After the message is queued, send the message to
# the specified address instead of the intended
# recipient(s).
#
# Note: this action overrides the FILTER action, and
# currently affects all recipients of the message.
#
# This feature is available in Postfix 2.1 and later.
#
# WARN optional text...
# Log a warning with the optional text, together with
# client information and if available, with helo,
# sender, recipient and protocol information.
#
# This feature is available in Postfix 2.1 and later.
#
# REGULAR EXPRESSION TABLES
# This section describes how the table lookups change when
# the table is given in the form of regular expressions. For
# a description of regular expression lookup table syntax,
# see regexp_table(5) or pcre_table(5).
#
# Each pattern is a regular expression that is applied to
# the entire string being looked up. Depending on the appli-
# cation, that string is an entire client hostname, an
# entire client IP address, or an entire mail address. Thus,
# no parent domain or parent network search is done,
# user@domain mail addresses are not broken up into their
# user@ and domain constituent parts, nor is user+foo broken
# up into user and foo.
#
# Patterns are applied in the order as specified in the ta-
# ble, until a pattern is found that matches the search
# string.
#
# Actions are the same as with indexed file lookups, with
# the additional feature that parenthesized substrings from
# the pattern can be interpolated as $1, $2 and so on.
#
# TCP-BASED TABLES
# This section describes how the table lookups change when
# lookups are directed to a TCP-based server. For a descrip-
# tion of the TCP client/server lookup protocol, see tcp_ta-
# ble(5). This feature is not available up to and including
# Postfix version 2.2.
#
# Each lookup operation uses the entire query string once.
# Depending on the application, that string is an entire
# client hostname, an entire client IP address, or an entire
# mail address. Thus, no parent domain or parent network
# search is done, user@domain mail addresses are not broken
# up into their user@ and domain constituent parts, nor is
# user+foo broken up into user and foo.
#
# Actions are the same as with indexed file lookups.
#
# EXAMPLE
# The following example uses an indexed file, so that the
# order of table entries does not matter. The example per-
# mits access by the client at address 1.2.3.4 but rejects
# all other clients in 1.2.3.0/24. Instead of hash lookup
# tables, some systems use dbm. Use the command "postconf
# -m" to find out what lookup tables Postfix supports on
# your system.
#
# /etc/postfix/main.cf:
# smtpd_client_restrictions =
# check_client_access hash:/etc/postfix/access
#
# /etc/postfix/access:
# 1.2.3 REJECT
# 1.2.3.4 OK
#
# Execute the command "postmap /etc/postfix/access" after
# editing the file.

# BUGS
# The table format does not understand quoting conventions.

# ALIASES(5) ALIASES(5)
#
# NAME
# aliases - Postfix local alias database format
#
# SYNOPSIS
# newaliases
#
# DESCRIPTION
# The aliases(5) table provides a system-wide mechanism to
# redirect mail for local recipients. The redirections are
# processed by the Postfix local(8) delivery agent.
#
# Normally, the aliases(5) table is specified as a text file
# that serves as input to the postalias(1) command. The
# result, an indexed file in dbm or db format, is used for
# fast lookup by the mail system. Execute the command
# newaliases in order to rebuild the indexed file after
# changing the Postfix alias database.
#
# The input and output file formats are expected to be com-
# patible with Sendmail version 8, and are expected to be
# suitable for the use as NIS maps.
#
# Users can control delivery of their own mail by setting up
# .forward files in their home directory. Lines in per-user
# .forward files have the same syntax as the right-hand side
# of aliases(5) entries.
#
# The format of the alias database input file is as follows:
#
# o An alias definition has the form
#
# name: value1, value2, ...
#
# o Empty lines and whitespace-only lines are ignored,
# as are lines whose first non-whitespace character
# is a `#'.
#
# o A logical line starts with non-whitespace text. A
# line that starts with whitespace continues a logi-
# cal line.
#
# The name is a local address (no domain part). Use double
# quotes when the name contains any special characters such
# as whitespace, `#', `:', or `@'. The name is folded to
# lowercase, in order to make database lookups case insensi-
# tive.
#
# In addition, when an alias exists for owner-name, delivery
# diagnostics are directed to that address, instead of to
# the originator. This is typically used to direct delivery
# errors to the owner of a mailing list, who is in a better
# position to deal with mailing list delivery problems than
# the originator of the undelivered mail.
#
# The value contains one or more of the following:
#
# address
# Mail is forwarded to address, which is compatible
# with the RFC 822 standard.
#
# /file/name
# Mail is appended to /file/name. See local(8) for
# details of delivery to file. Delivery is not lim-
# ited to regular files. For example, to dispose of
# unwanted mail, deflect it to /dev/null.
#
# |command
# Mail is piped into command. Commands that contain
# special characters, such as whitespace, should be
# enclosed between double quotes. See local(8) for
# details of delivery to command.
#
# When the command fails, a limited amount of command
# output is mailed back to the sender. The file
# /usr/include/sysexits.h defines the expected exit
# status codes. For example, use |"exit 67" to simu-
# late a "user unknown" error, and |"exit 0" to
# implement an expensive black hole.
#
# :include:/file/name
# Mail is sent to the destinations listed in the
# named file. Lines in :include: files have the same
# syntax as the right-hand side of alias entries.
#
# A destination can be any destination that is
# described in this manual page. However, delivery to
# "|command" and /file/name is disallowed by default.
# To enable, edit the allow_mail_to_commands and
# allow_mail_to_files configuration parameters.
#
# ADDRESS EXTENSION
# When alias database search fails, and the recipient local-
# part contains the optional recipient delimiter (e.g.,
# user+foo), the search is repeated for the unextended
# address (e.g., user).
#
# The propagate_unmatched_extensions parameter controls
# whether an unmatched address extension (+foo) is propa-
# gated to the result of table lookup.
#
# SECURITY
# The local(8) delivery agent disallows regular expression
# substitution of $1 etc. in alias_maps, because that would
# open a security hole.
#
# The local(8) delivery agent will silently ignore requests
# to use the proxymap(8) server within alias_maps. Instead
# it will open the table directly. Before Postfix version
# 2.2, the local(8) delivery agent will terminate with a
# fatal error.
#
# CONFIGURATION PARAMETERS
# The following main.cf parameters are especially relevant.
# The text below provides only a parameter summary. See
# postconf(5) for more details including examples.
#
# alias_database
# List of alias databases that are updated by the
# newaliases(1) command.
#
# alias_maps
# List of alias databases queried by the local(8)
# delivery agent.
#
# allow_mail_to_commands
# Restrict the usage of mail delivery to external
# command.
#
# allow_mail_to_files
# Restrict the usage of mail delivery to external
# file.
#
# expand_owner_alias
# When delivering to an alias that has an owner- com-
# panion alias, set the envelope sender address to
# the right-hand side of the owner alias, instead
# using of the left-hand side address.
#
# propagate_unmatched_extensions
# A list of address rewriting or forwarding mecha-
# nisms that propagate an address extension from the
# original address to the result. Specify zero or
# more of canonical, virtual, alias, forward,
# include, or generic.
#
# owner_request_special
# Give special treatment to owner-listname and list-
# name-request addresses.

# CANONICAL(5) CANONICAL(5)
#
# NAME
# canonical - Postfix canonical table format
#
# SYNOPSIS
# postmap /etc/postfix/canonical
#
# postmap -q "string" /etc/postfix/canonical
#
# postmap -q - /etc/postfix/canonical <inputfile
#
# DESCRIPTION
# The optional canonical(5) table specifies an address map-
# ping for local and non-local addresses. The mapping is
# used by the cleanup(8) daemon, before mail is stored into
# the queue. The address mapping is recursive.
#
# Normally, the canonical(5) table is specified as a text
# file that serves as input to the postmap(1) command. The
# result, an indexed file in dbm or db format, is used for
# fast searching by the mail system. Execute the command
# "postmap /etc/postfix/canonical" in order to rebuild the
# indexed file after changing the text file.
#
# When the table is provided via other means such as NIS,
# LDAP or SQL, the same lookups are done as for ordinary
# indexed files.
#
# Alternatively, the table can be provided as a regular-
# expression map where patterns are given as regular expres-
# sions, or lookups can be directed to TCP-based server. In
# that case, the lookups are done in a slightly different
# way as described below under "REGULAR EXPRESSION TABLES"
# and "TCP-BASED TABLES".
#
# By default the canonical(5) mapping affects both message
# header addresses (i.e. addresses that appear inside mes-
# sages) and message envelope addresses (for example, the
# addresses that are used in SMTP protocol commands). Think
# Sendmail rule set S3, if you like. This is controlled
# with the canonical_classes parameter.
#
# NOTE: Postfix versions 2.2 and later rewrite message head-
# ers from remote SMTP clients only if the client matches
# the local_header_rewrite_clients parameter, or if the
# remote_header_rewrite_domain configuration parameter spec-
# ifies a non-empty value. To get the behavior before Post-
# fix 2.2, specify "local_header_rewrite_clients =
# static:all".
#
# Typically, one would use the canonical(5) table to replace
# login names by Firstname.Lastname, or to clean up
# addresses produced by legacy mail systems.
#
# The canonical(5) mapping is not to be confused with vir-
# tual domain support. Use the virtual(5) map for that pur-
# pose.
#
# The canonical(5) mapping is not to be confused with local
# aliasing. Use the aliases(5) map for that purpose.
#
# TABLE FORMAT
# The input format for the postmap(1) command is as follows:
#
# pattern result
# When pattern matches a mail address, replace it by
# the corresponding result.
#
# blank lines and comments
# Empty lines and whitespace-only lines are ignored,
# as are lines whose first non-whitespace character
# is a `#'.
#
# multi-line text
# A logical line starts with non-whitespace text. A
# line that starts with whitespace continues a logi-
# cal line.
#
# TABLE SEARCH ORDER
# With lookups from indexed files such as DB or DBM, or from
# networked tables such as NIS, LDAP or SQL, patterns are
# tried in the order as listed below:
#
# user@domain address
# Replace user@domain by address. This form has the
# highest precedence.
#
# This is useful to clean up addresses produced by
# legacy mail systems. It can also be used to pro-
# duce Firstname.Lastname style addresses, but see
# below for a simpler solution.
#
# user address
# Replace user@site by address when site is equal to
# $myorigin, when site is listed in $mydestination,
# or when it is listed in $inet_interfaces or
# $proxy_interfaces.
#
# This form is useful for replacing login names by
# Firstname.Lastname.
#
# @domain address
# Replace other addresses in domain by address. This
# form has the lowest precedence.
#
# RESULT ADDRESS REWRITING
# The lookup result is subject to address rewriting:
#
# o When the result has the form @otherdomain, the
# result becomes the same user in otherdomain.
#
# o When "append_at_myorigin=yes", append "@$myorigin"
# to addresses without "@domain".
#
# o When "append_dot_mydomain=yes", append ".$mydomain"
# to addresses without ".domain".
#
# ADDRESS EXTENSION
# When a mail address localpart contains the optional recip-
# ient delimiter (e.g., user+foo@domain), the lookup order
# becomes: user+foo@domain, user@domain, user+foo, user, and
# @domain.
#
# The propagate_unmatched_extensions parameter controls
# whether an unmatched address extension (+foo) is propa-
# gated to the result of table lookup.
#
# REGULAR EXPRESSION TABLES
# This section describes how the table lookups change when
# the table is given in the form of regular expressions. For
# a description of regular expression lookup table syntax,
# see regexp_table(5) or pcre_table(5).

# string.
#
# Results are the same as with indexed file lookups, with

# GENERIC(5) GENERIC(5)
#
# NAME
# generic - Postfix generic table format
#
# SYNOPSIS
# postmap /etc/postfix/generic
#
# postmap -q "string" /etc/postfix/generic
#
# postmap -q - /etc/postfix/generic <inputfile
#
# DESCRIPTION
# The optional generic(5) table specifies an address mapping
# that applies when mail is delivered. This is the opposite
# of canonical(5) mapping, which applies when mail is
# received.
#
# Typically, one would use the generic(5) table on a system
# that does not have a valid Internet domain name and that
# uses something like localdomain.local instead. The
# generic(5) table is then used by the smtp(8) client to
# transform local mail addresses into valid Internet mail
# addresses when mail has to be sent across the Internet.
# See the EXAMPLE section at the end of this document.
#
# The generic(5) mapping affects both message header
# addresses (i.e. addresses that appear inside messages) and
# message envelope addresses (for example, the addresses
# that are used in SMTP protocol commands).
#
# Normally, the generic(5) table is specified as a text file
# that serves as input to the postmap(1) command. The
# result, an indexed file in dbm or db format, is used for
# fast searching by the mail system. Execute the command
# "postmap /etc/postfix/generic" in order to rebuild the
# indexed file after changing the text file.
#
# When the table is provided via other means such as NIS,
# LDAP or SQL, the same lookups are done as for ordinary
# indexed files.
#
# Alternatively, the table can be provided as a regular-
# expression map where patterns are given as regular expres-
# sions, or lookups can be directed to TCP-based server. In
# that case, the lookups are done in a slightly different
# way as described below under "REGULAR EXPRESSION TABLES"
# and "TCP-BASED TABLES".
#
# TABLE FORMAT
# The input format for the postmap(1) command is as follows:
#
# pattern result
# When pattern matches a mail address, replace it by
# the corresponding result.
#
# blank lines and comments
# Empty lines and whitespace-only lines are ignored,
# as are lines whose first non-whitespace character
# is a `#'.
#
# multi-line text
# A logical line starts with non-whitespace text. A
# line that starts with whitespace continues a logi-
# cal line.
#
# TABLE SEARCH ORDER
# With lookups from indexed files such as DB or DBM, or from
# networked tables such as NIS, LDAP or SQL, patterns are
# tried in the order as listed below:
#
# user@domain address
# Replace user@domain by address. This form has the
# highest precedence.
#
# user address
# Replace user@site by address when site is equal to
# $myorigin, when site is listed in $mydestination,
# or when it is listed in $inet_interfaces or
# $proxy_interfaces.
#
# @domain address
# Replace other addresses in domain by address. This
# form has the lowest precedence.
#
# RESULT ADDRESS REWRITING
# The lookup result is subject to address rewriting:
#
# o When the result has the form @otherdomain, the
# result becomes the same user in otherdomain.
#
# o When "append_at_myorigin=yes", append "@$myorigin"
# to addresses without "@domain".
#
# o When "append_dot_mydomain=yes", append ".$mydomain"
# to addresses without ".domain".
#
# ADDRESS EXTENSION
# When a mail address localpart contains the optional recip-
# ient delimiter (e.g., user+foo@domain), the lookup order
# becomes: user+foo@domain, user@domain, user+foo, user, and
# @domain.
#
# The propagate_unmatched_extensions parameter controls
# whether an unmatched address extension (+foo) is propa-
# gated to the result of table lookup.
#
# REGULAR EXPRESSION TABLES
# This section describes how the table lookups change when
# the table is given in the form of regular expressions. For
# a description of regular expression lookup table syntax,
# see regexp_table(5) or pcre_table(5).
#
# Each pattern is a regular expression that is applied to
# the entire address being looked up. Thus, user@domain mail
# addresses are not broken up into their user and @domain
# constituent parts, nor is user+foo broken up into user and
# foo.
#
# Patterns are applied in the order as specified in the
# table, until a pattern is found that matches the search
# string.
#
# Results are the same as with indexed file lookups, with
# the additional feature that parenthesized substrings from
# the pattern can be interpolated as $1, $2 and so on.
#
# TCP-BASED TABLES
# This section describes how the table lookups change when
# lookups are directed to a TCP-based server. For a descrip-
# tion of the TCP client/server lookup protocol, see
# tcp_table(5). This feature is not available up to and
# including Postfix version 2.2.
#
# Each lookup operation uses the entire address once. Thus,
# user@domain mail addresses are not broken up into their
# user and @domain constituent parts, nor is user+foo broken
# up into user and foo.
#
# Results are the same as with indexed file lookups.
#
# EXAMPLE
# The following shows a generic mapping with an indexed
# file. When mail is sent to a remote host via SMTP, this
# replaces his@localdomain.local by his ISP mail address,
# replaces her@localdomain.local by her ISP mail address,
# and replaces other local addresses by his ISP account,
# with an address extension of +local (this example assumes
# that the ISP supports "+" style address extensions).
#
# /etc/postfix/main.cf:
# smtp_generic_maps = hash:/etc/postfix/generic
#
# /etc/postfix/generic:
# his@localdomain.local hisaccount@hisisp.example
# her@localdomain.local heraccount@herisp.example
# @localdomain.local hisaccount+local@hisisp.example
#
# Execute the command "postmap /etc/postfix/generic" when-
# ever the table is changed. Instead of hash, some systems
# use dbm database files. To find out what tables your sys-
# tem supports use the command "postconf -m".
#
# BUGS
# The table format does not understand quoting conventions.

# HEADER_CHECKS(5) HEADER_CHECKS(5)
#
# NAME
# header_checks - Postfix built-in header/body inspection
#
# SYNOPSIS
# header_checks = pcre:/etc/postfix/header_checks
# mime_header_checks = pcre:/etc/postfix/mime_header_checks
# nested_header_checks = pcre:/etc/postfix/nested_header_checks
# body_checks = pcre:/etc/postfix/body_checks
#
# postmap -fq "string" pcre:/etc/postfix/filename
# postmap -fq - pcre:/etc/postfix/filename <inputfile
#
# DESCRIPTION
# Postfix provides a simple built-in content inspection
# mechanism that examines incoming mail one message header
# or one message body line at a time. Each input is compared
# against a list of patterns, and when a match is found the
# corresponding action is executed. This feature is imple-
# mented by the Postfix cleanup(8) server.
#
# For examples, see the EXAMPLES section at the end of this
# manual page.
#
# Postfix header or body_checks are designed to stop a flood
# of mail from worms or viruses; they do not decode attach-
# ments, and they do not unzip archives. See the documents
# referenced below in the README FILES section if you need
# more sophisticated content analysis.
#
# Postfix supports four built-in content inspection classes:
#
# header_checks
# These are applied to initial message headers
# (except for the headers that are processed with
# mime_header_checks).
#
# mime_header_checks (default: $header_checks)
# These are applied to MIME related message headers
# only.
#
# This feature is available in Postfix 2.0 and later.
#
# nested_header_checks (default: $header_checks)
# These are applied to message headers of attached
# email messages (except for the headers that are
# processed with mime_header_checks).
#
# This feature is available in Postfix 2.0 and later.
#
# body_checks
# These are applied to all other content, including
# multi-part message boundaries.
#
# With Postfix versions before 2.0, all content after
# the initial message headers is treated as body con-
# tent.
#
# Note: message headers are examined one logical header at a
# time, even when a message header spans multiple lines.
# Body lines are always examined one line at a time.
#
# TABLE FORMAT
# This document assumes that header and body_checks rules
# are specified in the form of Postfix regular expression
# lookup tables. Usually the best performance is obtained
# with pcre (Perl Compatible Regular Expression) tables, but
# the slower regexp (POSIX regular expressions) support is
# more widely available. Use the command "postconf -m" to
# find out what lookup table types your Postfix system sup-
# ports.
#
# The general format of Postfix regular expression tables is
# given below. For a discussion of specific pattern or
# flags syntax, see pcre_table(5) or regexp_table(5),
# respectively.
#
# /pattern/flags action
# When pattern matches the input string, execute the
# corresponding action. See below for a list of pos-
# sible actions.
#
# !/pattern/flags action
# When pattern does not match the input string, exe-
# cute the corresponding action.
#
# if /pattern/flags
#
# endif Match the input string against the patterns between
# if and endif, if and only if the input string also
# matches pattern. The if..endif can nest.
#
# Note: do not prepend whitespace to patterns inside
# if..endif.
#
# if !/pattern/flags
#
# endif Match the input string against the patterns between
# if and endif, if and only if the input string does
# not match pattern. The if..endif can nest.
#
# blank lines and comments
# Empty lines and whitespace-only lines are ignored,
# as are lines whose first non-whitespace character
# is a `#'.
#
# multi-line text
# A pattern/action line starts with non-whitespace
# text. A line that starts with whitespace continues
# a logical line.
#
# TABLE SEARCH ORDER
# For each line of message input, the patterns are applied
# in the order as specified in the table. When a pattern is
# found that matches the input line, the corresponding
# action is executed and then the next input line is
# inspected.
#
# TEXT SUBSTITUTION
# Substitution of substrings from the matched expression
# into the action string is possible using the conventional
# Perl syntax ($1, $2, etc.). The macros in the result
# string may need to be written as ${n} or $(n) if they
# aren't followed by whitespace.
#
# Note: since negated patterns (those preceded by !) return
# a result when the expression does not match, substitutions
# are not available for negated patterns.
#
# ACTIONS
# Action names are case insensitive. They are shown in upper
# case for consistency with other Postfix documentation.
#
# DISCARD optional text...
# Claim successful delivery and silently discard the
# message. Log the optional text if specified, oth-
# erwise log a generic message.
#
# Note: this action disables further header or
# body_checks inspection of the current message and
# affects all recipients.
#
# This feature is available in Postfix 2.0 and later.
#
# DUNNO Pretend that the input line did not match any pat-
# tern, and inspect the next input line. This action
# can be used to shorten the table search.
#
# For backwards compatibility reasons, Postfix also
# accepts OK but it is (and always has been) treated
# as DUNNO.
#
# This feature is available in Postfix 2.1 and later.
#
# FILTER transport:destination
# Write a content filter request to the queue file
# and inspect the next input line. After the com-
# plete message is received it will be sent through
# the specified external content filter. More infor-
# mation about external content filters is in the
# Postfix FILTER_README file.
#
# Note: this action overrides the main.cf con-
# tent_filter setting, and affects all recipients of
# the message. In the case that multiple FILTER
# actions fire, only the last one is executed.
#
# This feature is available in Postfix 2.0 and later.
#
# HOLD optional text...
# Arrange for the message to be placed on the hold
# queue, and inspect the next input line. The mes-
# sage remains on hold until someone either deletes
# it or releases it for delivery. Log the optional
# text if specified, otherwise log a generic message.
#
# Mail that is placed on hold can be examined with
# the postcat(1) command, and can be destroyed or
# released with the postsuper(1) command.
#
# Note: use "postsuper -r" to release mail that was
# kept on hold for a significant fraction of $maxi-
# mal_queue_lifetime or $bounce_queue_lifetime, or
# longer.
#
# Note: this action affects all recipients of the
# message.
#
# This feature is available in Postfix 2.0 and later.
#
# IGNORE Delete the current line from the input and inspect
# the next input line.
#
# PREPEND text...
# Prepend one line with the specified text and
# inspect the next input line.
#
# Notes:
#
# o The prepended text is output on a separate
# line, immediately before the input that
# triggered the PREPEND action.
#
# o The prepended text is not considered part of
# the input stream: it is not subject to
# header/body checks or address rewriting, and
# it does not affect the way that Postfix adds
# missing message headers.
#
# o When prepending text before a message header
# line, the prepended text must begin with a
# valid message header label.
#
# o This action cannot be used to prepend multi-
# line text.
#
# This feature is available in Postfix 2.1 and later.
#
# REDIRECT user@domain
# Write a message redirection request to the queue
# file and inspect the next input line. After the
# message is queued, it will be sent to the specified
# address instead of the intended recipient(s).
#
# Note: this action overrides the FILTER action, and
# affects all recipients of the message. If multiple
# REDIRECT actions fire, only the last one is exe-
# cuted.
#
# This feature is available in Postfix 2.1 and later.
#
# REPLACE text...
# Replace the current line with the specified text
# and inspect the next input line.
#
# This feature is available in Postfix 2.2 and later.
# The description below applies to Postfix 2.2.2 and
# later.
#
# Notes:
#
# o When replacing a message header line, the
# replacement text must begin with a valid
# header label.
#
# o The replaced text remains part of the input
# stream. Unlike the result from the PREPEND
# action, a replaced message header may be
# subject to address rewriting and may affect
# the way that Postfix adds missing message
# headers.
#
# REJECT optional text...
# Reject the entire message. Reply with optional
# text... when the optional text is specified, other-
# wise reply with a generic error message.
#
# Note: this action disables further header or
# body_checks inspection of the current message and
# affects all recipients.
#
# WARN optional text...
# Log a warning with the optional text... (or log a
# generic message) and inspect the next input line.
# This action is useful for debugging and for testing
# a pattern before applying more drastic actions.
#
# BUGS
# Many people overlook the main limitations of header and
# body_checks rules. These rules operate on one logical
# message header or one body line at a time, and a decision
# made for one line is not carried over to the next line.
# If text in the message body is encoded (RFC 2045) then the
# rules have to specified for the encoded form. Likewise,
# when message headers are encoded (RFC 2047) then the rules
# need to be specified for the encoded form.
#
# Message headers added by the cleanup(8) daemon itself are
# excluded from inspection. Examples of such message headers
# are From:, To:, Message-ID:, Date:.
#
# Message headers deleted by the cleanup(8) daemon will be
# examined before they are deleted. Examples are: Bcc:, Con-
# tent-Length:, Return-Path:.
#
# CONFIGURATION PARAMETERS
# body_checks
# Lookup tables with content filter rules for message
# body lines. These filters see one physical line at
# a time, in chunks of at most $line_length_limit
# bytes.
#
# body_checks_size_limit
# The amount of content per message body segment
# (attachment) that is subjected to $body_checks fil-
# tering.
#
# header_checks
#
# mime_header_checks (default: $header_checks)
#
# nested_header_checks (default: $header_checks)
# Lookup tables with content filter rules for message
# header lines: respectively, these are applied to
# the initial message headers (not including MIME
# headers), to the MIME headers anywhere in the mes-
# sage, and to the initial headers of attached mes-
# sages.
#
# Note: these filters see one logical message header
# at a time, even when a message header spans multi-
# ple lines. Message headers that are longer than
# $header_size_limit characters are truncated.
#
# disable_mime_input_processing
# While receiving mail, give no special treatment to
# MIME related message headers; all text after the
# initial message headers is considered to be part of
# the message body. This means that header_checks is
# applied to all the initial message headers, and
# that body_checks is applied to the remainder of the
# message.
#
# Note: when used in this manner, body_checks will
# process a multi-line message header one line at a
# time.
#
# EXAMPLES
# Header pattern to block attachments with bad file name
# extensions.
#
# /etc/postfix/main.cf:
# header_checks = regexp:/etc/postfix/header_checks
#
# /etc/postfix/header_checks:

# and /etc/aliases or their equivalent.
#
# The default is $myhostname + localhost.$mydomain. On a mail domain
# gateway, you should also include $mydomain.
#
# Do not specify the names of virtual domains - those domains are
# specified elsewhere (see VIRTUAL_README).
#
# Do not specify the names of domains that this machine is backup MX
# host for. Specify those names via the relay_domains settings for
# the SMTP server, or use permit_mx_backup if you are lazy (see
# STANDARD_CONFIGURATION_README).
#
# The local machine is always the final destination for mail addressed
# to user@[the.net.work.address] of an interface that the mail system
# receives mail on (see the inet_interfaces parameter).
#
# Specify a list of host or domain names, /file/name or type:table
# patterns, separated by commas and/or whitespace. A /file/name
# pattern is replaced by its contents; a type:table is matched when
# a name matches a lookup key (the right-hand side is ignored).
# Continue long lines by starting the next line with whitespace.
#
# See also below, section "REJECTING MAIL FOR UNKNOWN LOCAL USERS".
#
#mydestination = $myhostname, localhost.$mydomain, localhost
#mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
#mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain,
# mail.$mydomain, www.$mydomain, ftp.$mydomain
# REJECTING MAIL FOR UNKNOWN LOCAL USERS
#
# The local_recipient_maps parameter specifies optional lookup tables
# with all names or addresses of users that are local with respect
# to $mydestination, $inet_interfaces or $proxy_interfaces.
#
# If this parameter is defined, then the SMTP server will reject
# mail for unknown local users. This parameter is defined by default.
#
# To turn off local recipient checking in the SMTP server, specify
# local_recipient_maps = (i.e. empty).
#
# The default setting assumes that you use the default Postfix local
# delivery agent for local delivery. You need to update the
# local_recipient_maps setting if:
#
# - You define $mydestination domain recipients in files other than
# /etc/passwd, /etc/aliases, or the $virtual_alias_maps files.
# For example, you define $mydestination domain recipients in
# the $virtual_mailbox_maps files.
#
# - You redefine the local delivery agent in master.cf.
#
# - You redefine the "local_transport" setting in main.cf.
#
# - You use the "luser_relay", "mailbox_transport", or "fallback_transport"
# feature of the Postfix local delivery agent (see local(8)).
#
# Details are described in the LOCAL_RECIPIENT_README file.
#
# Beware: if the Postfix SMTP server runs chrooted, you probably have
# to access the passwd file via the proxymap service, in order to
# overcome chroot restrictions. The alternative, having a copy of
# the system passwd file in the chroot jail is just not practical.
#
# The right-hand side of the lookup tables is conveniently ignored.
# In the left-hand side, specify a bare username, an @domain.tld
# wild-card, or specify a user@domain.tld address.
#
#local_recipient_maps = unix:passwd.byname $alias_maps
#local_recipient_maps = proxy:unix:passwd.byname $alias_maps
#local_recipient_maps =
# The unknown_local_recipient_reject_code specifies the SMTP server
# response code when a recipient domain matches $mydestination or
# ${proxy,inet}_interfaces, while $local_recipient_maps is non-empty
# and the recipient address or address local-part is not found.
#
# The default setting is 550 (reject mail) but it is safer to start
# with 450 (try again later) until you are certain that your
# local_recipient_maps settings are OK.
#
unknown_local_recipient_reject_code = 550
# TRUST AND RELAY CONTROL
# The mynetworks parameter specifies the list of "trusted" SMTP
# clients that have more privileges than "strangers".
#
# In particular, "trusted" SMTP clients are allowed to relay mail
# through Postfix. See the smtpd_recipient_restrictions parameter
# in postconf(5).
#
# You can specify the list of "trusted" network addresses by hand
# or you can let Postfix do it for you (which is the default).
#
# By default (mynetworks_style = subnet), Postfix "trusts" SMTP
# clients in the same IP subnetworks as the local machine.
# On Linux, this does works correctly only with interfaces specified
# with the "ifconfig" command.
#
# Specify "mynetworks_style = class" when Postfix should "trust" SMTP
# clients in the same IP class A/B/C networks as the local machine.
# Don't do this with a dialup site - it would cause Postfix to "trust"
# your entire provider's network. Instead, specify an explicit
# mynetworks list by hand, as described below.
#
# Specify "mynetworks_style = host" when Postfix should "trust"
# only the local machine.
#
#mynetworks_style = class
#mynetworks_style = subnet
#mynetworks_style = host
# Alternatively, you can specify the mynetworks list by hand, in
# which case Postfix ignores the mynetworks_style setting.
#
# Specify an explicit list of network/netmask patterns, where the
# mask specifies the number of bits in the network part of a host
# address.
#
# You can also specify the absolute pathname of a pattern file instead
# of listing the patterns here. Specify type:table for table-based lookups
# (the value on the table right-hand side is not used).
#
#mynetworks = 168.100.189.0/28, 127.0.0.0/8
#mynetworks = $config_directory/mynetworks
#mynetworks = hash:/etc/postfix/network_table
# The relay_domains parameter restricts what destinations this system will
# relay mail to. See the smtpd_recipient_restrictions description in
# postconf(5) for detailed information.
#
# By default, Postfix relays mail
# - from "trusted" clients (IP address matches $mynetworks) to any destination,
# - from "untrusted" clients to destinations that match $relay_domains or
# subdomains thereof, except addresses with sender-specified routing.
# The default relay_domains value is $mydestination.
#
# In addition to the above, the Postfix SMTP server by default accepts mail
# that Postfix is final destination for:
# - destinations that match $inet_interfaces or $proxy_interfaces,
# - destinations that match $mydestination
# - destinations that match $virtual_alias_domains,
# - destinations that match $virtual_mailbox_domains.
# These destinations do not need to be listed in $relay_domains.
#
# Specify a list of hosts or domains, /file/name patterns or type:name
# lookup tables, separated by commas and/or whitespace. Continue
# long lines by starting the next line with whitespace. A file name
# is replaced by its contents; a type:name table is matched when a
# (parent) domain appears as lookup key.
#
# NOTE: Postfix will not automatically forward mail for domains that
# list this system as their primary or backup MX host. See the
# permit_mx_backup restriction description in postconf(5).
#
#relay_domains = $mydestination
# INTERNET OR INTRANET
# The relayhost parameter specifies the default host to send mail to
# when no entry is matched in the optional transport(5) table. When
# no relayhost is given, mail is routed directly to the destination.
#
# On an intranet, specify the organizational domain name. If your
# internal DNS uses no MX records, specify the name of the intranet
# gateway host instead.
#
# In the case of SMTP, specify a domain, host, host:port, [host]:port,
# [address] or [address]:port; the form [host] turns off MX lookups.
#
# If you're connected via UUCP, see also the default_transport parameter.

# REJECTING UNKNOWN RELAY USERS
#
# The relay_recipient_maps parameter specifies optional lookup tables
# with all addresses in the domains that match $relay_domains.
#
# If this parameter is defined, then the SMTP server will reject
# mail for unknown relay users. This feature is off by default.
#
# The right-hand side of the lookup tables is conveniently ignored.
# In the left-hand side, specify an @domain.tld wild-card, or specify
# a user@domain.tld address.
#
#relay_recipient_maps = hash:/etc/postfix/relay_recipients
# INPUT RATE CONTROL
#
# The in_flow_delay configuration parameter implements mail input
# flow control. This feature is turned on by default, although it
# still needs further development (it's disabled on SCO UNIX due
# to an SCO bug).
#
# A Postfix process will pause for $in_flow_delay seconds before
# accepting a new message, when the message arrival rate exceeds the
# message delivery rate. With the default 100 SMTP server process
# limit, this limits the mail inflow to 100 messages a second more
# than the number of messages delivered per second.
#
# Specify 0 to disable the feature. Valid delays are 0..10.
#
#in_flow_delay = 1s
# ADDRESS REWRITING
#
# The ADDRESS_REWRITING_README document gives information about
# address masquerading or other forms of address rewriting including
# username->Firstname.Lastname mapping.
# ADDRESS REDIRECTION (VIRTUAL DOMAIN)
#
# The VIRTUAL_README document gives information about the many forms
# of domain hosting that Postfix supports.

#
# See the discussion in the ADDRESS_REWRITING_README document.
# TRANSPORT MAP
#
# See the discussion in the ADDRESS_REWRITING_README document.
# ALIAS DATABASE
#
# The alias_maps parameter specifies the list of alias databases used
# by the local delivery agent. The default list is system dependent.
#
# On systems with NIS, the default is to search the local alias
# database, then the NIS alias database. See aliases(5) for syntax
# details.
#
# If you change the alias database, run "postalias /etc/aliases" (or
# wherever your system stores the mail alias file), or simply run
# "newaliases" to build the necessary DBM or DB file.
#
# It will take a minute or so before changes become visible. Use
# "postfix reload" to eliminate the delay.
#
#alias_maps = dbm:/etc/aliases
#alias_maps = hash:/etc/aliases
#alias_maps = hash:/etc/aliases, nis:mail.aliases
#alias_maps = netinfo:/aliases
# The alias_database parameter specifies the alias database(s) that
# are built with "newaliases" or "sendmail -bi". This is a separate
# configuration parameter, because alias_maps (see above) may specify
# tables that are not necessarily all under control by Postfix.
#
#alias_database = dbm:/etc/aliases
#alias_database = dbm:/etc/mail/aliases
#alias_database = hash:/etc/aliases
#alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases
# ADDRESS EXTENSIONS (e.g., user+foo)
#
# The recipient_delimiter parameter specifies the separator between
# user names and address extensions (user+foo). See canonical(5),
# local(8), relocated(5) and virtual(5) for the effects this has on
# aliases, canonical, virtual, relocated and .forward file lookups.
# Basically, the software tries user+foo and .forward+foo before
# trying user and .forward.
#
#recipient_delimiter = +
# DELIVERY TO MAILBOX
#
# The home_mailbox parameter specifies the optional pathname of a
# mailbox file relative to a user's home directory. The default
# mailbox file is /var/spool/mail/user or /var/mail/user. Specify
# "Maildir/" for qmail-style delivery (the / is required).
#
#home_mailbox = Mailbox
#home_mailbox = Maildir/
# The mail_spool_directory parameter specifies the directory where
# UNIX-style mailboxes are kept. The default setting depends on the
# system type.
#
#mail_spool_directory = /var/mail
#mail_spool_directory = /var/spool/mail
# The mailbox_command parameter specifies the optional external
# command to use instead of mailbox delivery. The command is run as
# the recipient with proper HOME, SHELL and LOGNAME environment settings.
# Exception: delivery for root is done as $default_user.
#
# Other environment variables of interest: USER (recipient username),
# EXTENSION (address extension), DOMAIN (domain part of address),
# and LOCAL (the address localpart).
#
# Unlike other Postfix configuration parameters, the mailbox_command
# parameter is not subjected to $parameter substitutions. This is to
# make it easier to specify shell syntax (see example below).
#
# Avoid shell meta characters because they will force Postfix to run
# an expensive shell process. Procmail alone is expensive enough.
#
# IF YOU USE THIS TO DELIVER MAIL SYSTEM-WIDE, YOU MUST SET UP AN
# ALIAS THAT FORWARDS MAIL FOR ROOT TO A REAL USER.
#
#mailbox_command = /some/where/procmail
#mailbox_command = /some/where/procmail -a "$EXTENSION"
# The mailbox_transport specifies the optional transport in master.cf
# to use after processing aliases and .forward files. This parameter
# has precedence over the mailbox_command, fallback_transport and
# luser_relay parameters.
#
# Specify a string of the form transport:nexthop, where transport is
# the name of a mail delivery transport defined in master.cf. The
# :nexthop part is optional. For more details see the sample transport
# configuration file.
#
# NOTE: if you use this feature for accounts not in the UNIX password
# file, then you must update the "local_recipient_maps" setting in
# the main.cf file, otherwise the SMTP server will reject mail for
# non-UNIX accounts with "User unknown in local recipient table".
#
#mailbox_transport = lmtp:unix:/file/name
#mailbox_transport = cyrus
# The fallback_transport specifies the optional transport in master.cf
# to use for recipients that are not found in the UNIX passwd database.
# This parameter has precedence over the luser_relay parameter.
#
# Specify a string of the form transport:nexthop, where transport is
# the name of a mail delivery transport defined in master.cf. The

#
#fallback_transport = lmtp:unix:/file/name
#fallback_transport = cyrus
#fallback_transport =
# The luser_relay parameter specifies an optional destination address
# for unknown recipients. By default, mail for unknown@$mydestination,
# unknown@[$inet_interfaces] or unknown@[$proxy_interfaces] is returned
# as undeliverable.
#
# The following expansions are done on luser_relay: $user (recipient
# username), $shell (recipient shell), $home (recipient home directory),
# $recipient (full recipient address), $extension (recipient address
# extension), $domain (recipient domain), $local (entire recipient
# localpart), $recipient_delimiter. Specify ${name?value} or
# ${name:value} to expand value only when $name does (does not) exist.
#
# luser_relay works only for the default Postfix local delivery agent.
#
# NOTE: if you use this feature for accounts not in the UNIX password

# JUNK MAIL CONTROLS
#
# The controls listed here are only a very small subset. The file
# SMTPD_ACCESS_README provides an overview.
# The header_checks parameter specifies an optional table with patterns
# that each logical message header is matched against, including
# headers that span multiple physical lines.
#
# By default, these patterns also apply to MIME headers and to the
# headers of attached messages. With older Postfix versions, MIME and
# attached message headers were treated as body text.
#
# For details, see "man header_checks".
#
#header_checks = regexp:/etc/postfix/header_checks
# FAST ETRN SERVICE
#
# Postfix maintains per-destination logfiles with information about
# deferred mail, so that mail can be flushed quickly with the SMTP
# "ETRN domain.tld" command, or by executing "sendmail -qRdomain.tld".
# See the ETRN_README document for a detailed description.
#
# The fast_flush_domains parameter controls what destinations are
# eligible for this service. By default, they are all domains that
# this server is willing to relay mail to.
#
#fast_flush_domains = $relay_domains
# SHOW SOFTWARE VERSION OR NOT
#
# The smtpd_banner parameter specifies the text that follows the 220
# code in the SMTP server's greeting banner. Some people like to see
# the mail version advertised. By default, Postfix shows no version.
#
# You MUST specify $myhostname at the start of the text. That is an
# RFC requirement. Postfix itself does not care.
#
#smtpd_banner = $myhostname ESMTP $mail_name
#smtpd_banner = $myhostname ESMTP $mail_name ($mail_version)
# PARALLEL DELIVERY TO THE SAME DESTINATION
#
# How many parallel deliveries to the same user or domain? With local
# delivery, it does not make sense to do massively parallel delivery
# to the same user, because mailbox updates must happen sequentially,
# and expensive pipelines in .forward files can cause disasters when
# too many are run at the same time. With SMTP deliveries, 10
# simultaneous connections to the same domain could be sufficient to
# raise eyebrows.
#
# Each message delivery transport has its XXX_destination_concurrency_limit
# parameter. The default is $default_destination_concurrency_limit for
# most delivery transports. For the local delivery agent the default is 2.
#local_destination_concurrency_limit = 2
#default_destination_concurrency_limit = 20
# DEBUGGING CONTROL
#
# The debug_peer_level parameter specifies the increment in verbose
# logging level when an SMTP client or server host name or address
# matches a pattern in the debug_peer_list parameter.
#
debug_peer_level = 2
# The debug_peer_list parameter specifies an optional list of domain
# or network patterns, /file/name patterns or type:name tables. When
# an SMTP client or server host name or address matches a pattern,
# increase the verbose logging level by the amount specified in the
# debug_peer_level parameter.
#
#debug_peer_list = 127.0.0.1
#debug_peer_list = some.domain
# The debugger_command specifies the external command that is executed
# when a Postfix daemon program is run with the -D option.
#
# Use "command .. & sleep 5" so that the debugger can attach before
# the process marches on. If you use an X-based debugger, be sure to
# set up your XAUTHORITY environment variable before starting Postfix.
#
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
xxgdb $daemon_directory/$process_name $process_id & sleep 5

#
# Another possibility is to run gdb under a detached screen session.
# To attach to the screen sesssion, su root and run "screen -r

# RELOCATED(5) RELOCATED(5)
#
# NAME
# relocated - Postfix relocated table format
#
# SYNOPSIS
# postmap /etc/postfix/relocated
#
# DESCRIPTION
# The optional relocated(5) table provides the information
# that is used in "user has moved to new_location" bounce
# messages.
#
# Normally, the relocated(5) table is specified as a text
# file that serves as input to the postmap(1) command. The
# result, an indexed file in dbm or db format, is used for
# fast searching by the mail system. Execute the command
# "postmap /etc/postfix/relocated" in order to rebuild the
# indexed file after changing the relocated table.
#
# When the table is provided via other means such as NIS,
# LDAP or SQL, the same lookups are done as for ordinary
# indexed files.
#
# Alternatively, the table can be provided as a regular-
# expression map where patterns are given as regular expres-
# sions, or lookups can be directed to TCP-based server. In
# that case, the lookups are done in a slightly different
# way as described below under "REGULAR EXPRESSION TABLES"
# and "TCP-BASED TABLES".
#
# Table lookups are case insensitive.
#
# TABLE FORMAT
# The input format for the postmap(1) command is as follows:
#
# o An entry has one of the following form:
# pattern new_location
# Where new_location specifies contact information
# such as an email address, or perhaps a street
# address or telephone number.
#
# o Empty lines and whitespace-only lines are ignored,
# as are lines whose first non-whitespace character
# is a `#'.
#
# o A logical line starts with non-whitespace text. A
# line that starts with whitespace continues a logi-
# cal line.
#
# TABLE SEARCH ORDER
# With lookups from indexed files such as DB or DBM, or from
# networked tables such as NIS, LDAP or SQL, patterns are
# tried in the order as listed below:
#
# user@domain
# Matches user@domain. This form has precedence over
# all other forms.
#
# user Matches user@site when site is $myorigin, when site
# is listed in $mydestination, or when site is listed
# in $inet_interfaces or $proxy_interfaces.
#
# @domain
# Matches other addresses in domain. This form has
# the lowest precedence.
#
# ADDRESS EXTENSION
# When a mail address localpart contains the optional recip-
# ient delimiter (e.g., user+foo@domain), the lookup order
# becomes: user+foo@domain, user@domain, user+foo, user, and
# @domain.
#
# REGULAR EXPRESSION TABLES
# This section describes how the table lookups change when
# the table is given in the form of regular expressions or
# when lookups are directed to a TCP-based server. For a
# description of regular expression lookup table syntax, see
# regexp_table(5) or pcre_table(5). For a description of the
# TCP client/server table lookup protocol, see tcp_table(5).
# This feature is not available up to and including Postfix
# version 2.2.
#
# Each pattern is a regular expression that is applied to
# the entire address being looked up. Thus, user@domain mail
# addresses are not broken up into their user and @domain
# constituent parts, nor is user+foo broken up into user and
# foo.
#
# Patterns are applied in the order as specified in the ta-
# ble, until a pattern is found that matches the search
# string.
#
# Results are the same as with indexed file lookups, with
# the additional feature that parenthesized substrings from
# the pattern can be interpolated as $1, $2 and so on.
#
# TCP-BASED TABLES
# This section describes how the table lookups change when
# lookups are directed to a TCP-based server. For a descrip-
# tion of the TCP client/server lookup protocol, see tcp_ta-
# ble(5). This feature is not available up to and including
# Postfix version 2.2.
#

# TRANSPORT(5) TRANSPORT(5)
#
# NAME
# transport - Postfix transport table format
#
# SYNOPSIS
# postmap /etc/postfix/transport
#
# postmap -q "string" /etc/postfix/transport
#
# postmap -q - /etc/postfix/transport <inputfile
#
# DESCRIPTION
# The optional transport(5) table specifies a mapping from
# email addresses to message delivery transports and/or
# relay hosts. The mapping is used by the trivial-rewrite(8)
# daemon.
#
# This mapping overrides the default routing that is built
# into Postfix:
#
# mydestination
# A list of domains that is by default delivered via
# $local_transport. This also includes domains that
# match $inet_interfaces or $proxy_interfaces.
#
# virtual_mailbox_domains
# A list of domains that is by default delivered via
# $virtual_transport.
#
# relay_domains
# A list of domains that is by default delivered via
# $relay_transport.
#
# any other destination
# Mail for any other destination is by default deliv-
# ered via $default_transport.
#
# Normally, the transport(5) table is specified as a text
# file that serves as input to the postmap(1) command. The
# result, an indexed file in dbm or db format, is used for
# fast searching by the mail system. Execute the command
# "postmap /etc/postfix/transport" in order to rebuild the
# indexed file after changing the transport table.
#
# When the table is provided via other means such as NIS,
# LDAP or SQL, the same lookups are done as for ordinary
# indexed files.
#
# Alternatively, the table can be provided as a regular-
# expression map where patterns are given as regular expres-
# sions, or lookups can be directed to TCP-based server. In
# that case, the lookups are done in a slightly different
# way as described below under "REGULAR EXPRESSION TABLES"
# and "TCP-BASED TABLES".
#
# TABLE FORMAT
# The input format for the postmap(1) command is as follows:
#
# pattern result
# When pattern matches the recipient address or
# domain, use the corresponding result.
#
# blank lines and comments
# Empty lines and whitespace-only lines are ignored,
# as are lines whose first non-whitespace character
# is a `#'.
#
# multi-line text
# A logical line starts with non-whitespace text. A
# line that starts with whitespace continues a logi-
# cal line.
#
# The pattern specifies an email address, a domain name, or
# a domain name hierarchy, as described in section "TABLE
# LOOKUP".
#
# The result is of the form transport:nexthop and specifies
# how or where to deliver mail. This is described in section
# "RESULT FORMAT".
#
# TABLE SEARCH ORDER
# With lookups from indexed files such as DB or DBM, or from
# networked tables such as NIS, LDAP or SQL, patterns are
# tried in the order as listed below:
#
# user+extension@domain transport:nexthop
# Deliver mail for user+extension@domain through
# transport to nexthop.
#
# user@domain transport:nexthop
# Deliver mail for user@domain through transport to
# nexthop.
#
# domain transport:nexthop
# Deliver mail for domain through transport to nex-
# thop.
#
# .domain transport:nexthop
# Deliver mail for any subdomain of domain through
# transport to nexthop. This applies only when the
# string transport_maps is not listed in the par-
# ent_domain_matches_subdomains configuration set-
# ting. Otherwise, a domain name matches itself and
# its subdomains.
#
# Note 1: the special pattern * represents any address (i.e.
# it functions as the wild-card pattern).
#
# Note 2: the null recipient address is looked up as
# $empty_address_recipient@$myhostname (default: mailer-dae-
# mon@hostname).
#
# Note 3: user@domain or user+extension@domain lookup is
# available in Postfix 2.0 and later.
#
# RESULT FORMAT
# The lookup result is of the form transport:nexthop. The
# transport field specifies a mail delivery transport such
# as smtp or local. The nexthop field specifies where and
# how to deliver mail.
#
# The transport field specifies the name of a mail delivery
# transport (the first name of a mail delivery service entry
# in the Postfix master.cf file).
#
# The interpretation of the nexthop field is transport
# dependent. In the case of SMTP, specify a service on a
# non-default port as host:service, and disable MX (mail
# exchanger) DNS lookups with [host] or [host]:port. The []
# form is required when you specify an IP address instead of
# a hostname.
#
# A null transport and null nexthop result means "do not
# change": use the delivery transport and nexthop informa-
# tion that would be used when the entire transport table
# did not exist.
#
# A non-null transport field with a null nexthop field
# resets the nexthop information to the recipient domain.
#
# A null transport field with non-null nexthop field does
# not modify the transport information.
#
# EXAMPLES
# In order to deliver internal mail directly, while using a
# mail relay for all other mail, specify a null entry for
# internal destinations (do not change the delivery trans-
# port or the nexthop information) and specify a wildcard
# for all other destinations.
#
# my.domain :
# .my.domain :
# * smtp:outbound-relay.my.domain
#
# In order to send mail for example.com and its subdomains
# via the uucp transport to the UUCP host named example:
#
# example.com uucp:example
# .example.com uucp:example
#
# When no nexthop host name is specified, the destination
# domain name is used instead. For example, the following
# directs mail for user@example.com via the slow transport
# to a mail exchanger for example.com. The slow transport
# could be configured to run at most one delivery process at
# a time:
#
# example.com slow:
#
# When no transport is specified, Postfix uses the transport
# that matches the address domain class (see DESCRIPTION
# above). The following sends all mail for example.com and
# its subdomains to host gateway.example.com:
#
# example.com :[gateway.example.com]
# .example.com :[gateway.example.com]
#
# In the above example, the [] suppress MX lookups. This
# prevents mail routing loops when your machine is primary
# MX host for example.com.
#
# In the case of delivery via SMTP, one may specify host-
# name:service instead of just a host:
#
# example.com smtp:bar.example:2025
#
# This directs mail for user@example.com to host bar.example
# port 2025. Instead of a numerical port a symbolic name may
# be used. Specify [] around the hostname if MX lookups must
# be disabled.
#
# The error mailer can be used to bounce mail:
#
# .example.com error:mail for *.example.com is not
# deliverable
#
# This causes all mail for user@anything.example.com to be
# bounced.
#
# REGULAR EXPRESSION TABLES
# This section describes how the table lookups change when
# the table is given in the form of regular expressions. For
# a description of regular expression lookup table syntax,
# see regexp_table(5) or pcre_table(5).
#
# Each pattern is a regular expression that is applied to
# the entire address being looked up. Thus,
# some.domain.hierarchy is not looked up via its parent
# domains, nor is user+foo@domain looked up as user@domain.
#
# Patterns are applied in the order as specified in the
# table, until a pattern is found that matches the search
# string.
#
# Results are the same as with indexed file lookups, with
# the additional feature that parenthesized substrings from
# the pattern can be interpolated as $1, $2 and so on.
#
# TCP-BASED TABLES
# This section describes how the table lookups change when
# lookups are directed to a TCP-based server. For a descrip-
# tion of the TCP client/server lookup protocol, see
# tcp_table(5). This feature is not available up to and
# including Postfix version 2.2.
#
# Each lookup operation uses the entire recipient address
# once. Thus, some.domain.hierarchy is not looked up via
# its parent domains, nor is user+foo@domain looked up as
# user@domain.
#
# Results are the same as with indexed file lookups.
#
# CONFIGURATION PARAMETERS
# The following main.cf parameters are especially relevant.
# The text below provides only a parameter summary. See
# postconf(5) for more details including examples.
#
# empty_address_recipient
# The address that is looked up instead of the null
# sender address.
#
# parent_domain_matches_subdomains
# List of Postfix features that use domain.tld pat-
# terns to match sub.domain.tld (as opposed to
# requiring .domain.tld patterns).

# VIRTUAL(5) VIRTUAL(5)
#
# NAME
# virtual - Postfix virtual alias table format
#
# SYNOPSIS
# postmap /etc/postfix/virtual
#
# postmap -q "string" /etc/postfix/virtual
#
# postmap -q - /etc/postfix/virtual <inputfile
#
# DESCRIPTION
# The optional virtual(5) alias table rewrites recipient
# addresses for all local, virtual and remote mail destina-
# tions. This is unlike the aliases(5) table which is used
# only for local(8) delivery. Virtual aliasing is recur-
# sive, and is implemented by the Postfix cleanup(8) daemon
# before mail is queued.
#
# The main applications of virtual aliasing are:
#
# o To redirect mail for one address to one or more
# addresses.
#
# o To implement virtual alias domains where all
# addresses are aliased to addresses in other
# domains.
#
# Virtual alias domains are not to be confused with
# the virtual mailbox domains that are implemented
# with the Postfix virtual(8) mail delivery agent.
# With virtual mailbox domains, each recipient
# address can have its own mailbox.
#
# Virtual aliasing is applied only to recipient envelope
# addresses, and does not affect message headers. Think
# Sendmail rule set S0, if you like. Use canonical(5) map-
# ping to rewrite header and envelope addresses in general.
#
# Normally, the virtual(5) alias table is specified as a
# text file that serves as input to the postmap(1) command.
# The result, an indexed file in dbm or db format, is used
# for fast searching by the mail system. Execute the command
# "postmap /etc/postfix/virtual" in order to rebuild the
# indexed file after changing the text file.
#
# When the table is provided via other means such as NIS,
# LDAP or SQL, the same lookups are done as for ordinary
# indexed files.
#
# Alternatively, the table can be provided as a regular-
# expression map where patterns are given as regular expres-
# sions, or lookups can be directed to TCP-based server. In
# that case, the lookups are done in a slightly different
# way as described below under "REGULAR EXPRESSION TABLES"
# and "TCP-BASED TABLES".
#
# TABLE FORMAT
# The input format for the postmap(1) command is as follows:
#
# pattern result
# When pattern matches a mail address, replace it by
# the corresponding result.
#
# blank lines and comments
# Empty lines and whitespace-only lines are ignored,
# as are lines whose first non-whitespace character
# is a `#'.
#
# multi-line text
# A logical line starts with non-whitespace text. A
# line that starts with whitespace continues a logi-
# cal line.
#
# TABLE SEARCH ORDER
# With lookups from indexed files such as DB or DBM, or from
# networked tables such as NIS, LDAP or SQL, patterns are
# tried in the order as listed below:
#
# user@domain address, address, ...
# Redirect mail for user@domain to address. This
# form has the highest precedence.
#
# user address, address, ...
# Redirect mail for user@site to address when site is
# equal to $myorigin, when site is listed in $mydes-
# tination, or when it is listed in $inet_interfaces
# or $proxy_interfaces.
#
# This functionality overlaps with functionality of
# the local aliases(5) database. The difference is
# that virtual(5) mapping can be applied to non-local
# addresses.
#
# @domain address, address, ...
# Redirect mail for other users in domain to address.
# This form has the lowest precedence.
#
# RESULT ADDRESS REWRITING
# The lookup result is subject to address rewriting:
#
# o When the result has the form @otherdomain, the
# result becomes the same user in otherdomain. This
# works only for the first address in a multi-address
# lookup result.
#
# o When "append_at_myorigin=yes", append "@$myorigin"
# to addresses without "@domain".
#
# o When "append_dot_mydomain=yes", append ".$mydomain"
# to addresses without ".domain".
#
# ADDRESS EXTENSION
# When a mail address localpart contains the optional recip-
# ient delimiter (e.g., user+foo@domain), the lookup order
# becomes: user+foo@domain, user@domain, user+foo, user, and
# @domain.
#
# The propagate_unmatched_extensions parameter controls
# whether an unmatched address extension (+foo) is propa-
# gated to the result of table lookup.
#
# VIRTUAL ALIAS DOMAINS
# Besides virtual aliases, the virtual alias table can also
# be used to implement virtual alias domains. With a virtual
# alias domain, all recipient addresses are aliased to
# addresses in other domains.
#
# Virtual alias domains are not to be confused with the vir-
# tual mailbox domains that are implemented with the Postfix
# virtual(8) mail delivery agent. With virtual mailbox
# domains, each recipient address can have its own mailbox.
#
# With a virtual alias domain, the virtual domain has its
# own user name space. Local (i.e. non-virtual) usernames
# are not visible in a virtual alias domain. In particular,
# local aliases(5) and local mailing lists are not visible
# as localname@virtual-alias.domain.
#
# Support for a virtual alias domain looks like:
#
# /etc/postfix/main.cf:
# virtual_alias_maps = hash:/etc/postfix/virtual
#
# Note: some systems use dbm databases instead of hash.
# See the output from "postconf -m" for available data-
# base types.
#
# /etc/postfix/virtual:
# virtual-alias.domain anything (right-hand content does not matter)
# postmaster@virtual-alias.domain postmaster
# user1@virtual-alias.domain address1
# user2@virtual-alias.domain address2, address3
#
# The virtual-alias.domain anything entry is required for a
# virtual alias domain. Without this entry, mail is rejected
# with "relay access denied", or bounces with "mail loops
# back to myself".
#
# Do not specify virtual alias domain names in the main.cf
# mydestination or relay_domains configuration parameters.
#
# With a virtual alias domain, the Postfix SMTP server
# accepts mail for known-user@virtual-alias.domain, and
# rejects mail for unknown-user@virtual-alias.domain as
# undeliverable.
#
# Instead of specifying the virtual alias domain name via
# the virtual_alias_maps table, you may also specify it via
# the main.cf virtual_alias_domains configuration parameter.
# This latter parameter uses the same syntax as the main.cf
# mydestination configuration parameter.
#
# REGULAR EXPRESSION TABLES
# This section describes how the table lookups change when
# the table is given in the form of regular expressions. For
# a description of regular expression lookup table syntax,
# see regexp_table(5) or pcre_table(5).
#
# Each pattern is a regular expression that is applied to

# ble, until a pattern is found that matches the search
# string.
#
# Results are the same as with indexed file lookups, with
