Log the optional text if specified, oth- +# erwise log a generic message. +# +# Note: this action currently affects all recipients +# of the message. To discard only one recipient +# without discarding the entire message, use the +# transport(5) table to direct mail to the discard(8) +# service. +# +# This feature is available in Postfix 2.0 and later. +# +# DUNNO Pretend that the lookup key was not found.

More information about external content +# filters is in the Postfix FILTER_README file. +# +# Note 1: do not use $number regular expression sub- +# stitutions for transport or destination unless you +# know that the information has a trusted origin. +# +# Note 2: 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. +# +# Note 3: the purpose of the FILTER command is to +# override message routing. To override the recipi- +# ent's transport but not the next-hop destination, +# specify an empty filter destination (Postfix 2.7 +# and later), or specify a transport:destination that +# delivers through a different Postfix instance +# (Postfix 2.6 and earlier). Other options are using +# the recipient-dependent transport_maps or the sen- +# der-dependent sender_dependent_default_transport- +# _maps features. +# +# 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. Use "postsuper -H" only for mail that will +# not expire within a few delivery attempts. +# +# 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 more than one PREPEND action executes, +# the first prepended header appears before the sec- +# ond etc. prepended header. +# +# Note: this action must execute before the message +# content is received; it cannot execute in the con- +# text of 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). When multiple REDIRECT actions fire, +# only the last one takes effect. +# +# Note: this action overrides the FILTER action, and +# currently overrides all recipients of the message. +# +# This feature is available in Postfix 2.1 and later. +# +# INFO optional text... +# Log an informational record with the optional text, +# together with client information and if available, +# with helo, sender, recipient and protocol informa- +# tion. +# +# This feature is available in Postfix 3.0 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. +# +# ENHANCED STATUS CODES +# Postfix version 2.3 and later support enhanced status +# codes as defined in RFC 3463. When an enhanced status +# code is specified in an access table, it is subject to +# modification. The following transformations are needed +# when the same access table is used for client, helo, +# sender, or recipient access restrictions; they happen +# regardless of whether Postfix replies to a MAIL FROM, RCPT +# TO or other SMTP command. +# +# o When a sender address matches a REJECT action, the +# Postfix SMTP server will transform a recipient DSN +# status (e.g., 4.1.1-4.1.6) into the corresponding +# sender DSN status, and vice versa. +# +# o When non-address information matches a REJECT +# action (such as the HELO command argument or the +# client hostname/address), the Postfix SMTP server +# will transform a sender or recipient DSN status +# into a generic non-address DSN status (e.g., +# 4.0.0). +# +# 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 2.4. +# +# 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.

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. +# +# 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 regu- +# lar-expression map where patterns are given as regular +# expressions. In this case, the lookups are done in a +# slightly different way as described below under "REGULAR +# EXPRESSION TABLES". +# +# 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, this +# will override the envelope sender address, so that deliv- +# ery diagnostics are directed to owner-name, instead of the +# originator of the message (for details, see +# owner_request_special, expand_owner_alias and +# reset_owner_alias). This is typically used to direct +# delivery errors to the maintainer 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. +# +# CASE FOLDING +# The local(8) delivery agent always folds the search string +# to lowercase before database 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). NOTE: these formats +# do not use ":" at the end of a pattern. +# +# Each regular expression is applied to the entire search +# string. Thus, a search string user+foo is not broken up +# into user and foo. +# +# Regular expressions are applied in the order as specified +# in the table, until a regular expression is found that +# matches the search string. +# +# Lookup results are the same as with indexed file lookups. +# For security reasons there is no support for $1, $2 etc. +# substring interpolation. +# +# 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.

To find these documents, use +# the command "postconf html_directory readme_directory", or go to +# http://www.postfix.org/BASIC_CONFIGURATION_README.html etc. +# +# For best results, change no more than 2-3 parameters at a time, +# and test if Postfix still works after every change. + +# COMPATIBILITY +# +# The compatibility_level determines what default settings Postfix +# will use for main.cf and master.cf settings. These defaults will +# change over time. +# +# To avoid breaking things, Postfix will use backwards-compatible +# default settings and log where it uses those old backwards-compatible +# default settings, until the system administrator has determined +# if any backwards-compatible default settings need to be made +# permanent in main.cf or master.cf. +# +# When this review is complete, update the compatibility_level setting +# below as recommended in the RELEASE_NOTES file. +# +# The level below is what should be used with new (not upgrade) installs. +# +compatibility_level = 2 + +# SOFT BOUNCE +# +# The soft_bounce parameter provides a limited safety net for +# testing.

/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" to rebuild an indexed +# file after changing the corresponding 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 regu- +# lar-expression map where patterns are given as regular +# expressions, or lookups can be directed to TCP-based +# server. In those case, the lookups are done in a slightly +# different way as described below under "REGULAR EXPRESSION +# TABLES" or "TCP-BASED TABLES". +# +# Table lookups are case insensitive. +# +# CASE FOLDING +# The search string is folded to lowercase before database +# lookup. As of Postfix 2.3, the search string is not case +# folded with database types such as regexp: or pcre: whose +# lookup fields can match both upper and lower case. +# +# 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 2.4. +# +# 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 2.4. +# +# 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. +# +# BUGS +# The table format does not understand quoting conventions. +# +# 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. +# +# relocated_maps +# List of lookup tables for relocated users or sites. +# +# Other parameters of interest: +# +# inet_interfaces +# The network interface addresses that this system +# receives mail on.
