#
# 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.
#
# 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. 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 (see 'postconf -d' output)
# The alias databases for local(8) delivery that are
# updated with "newaliases" or with "sendmail -bi".
#
# alias_maps (see 'postconf -d' output)
# The alias databases that are used for local(8)
# delivery.
#
# allow_mail_to_commands (alias, forward)
# Restrict local(8) mail delivery to external com-
# mands.
#
# allow_mail_to_files (alias, forward)
# Restrict local(8) mail delivery to external files.
#
# expand_owner_alias (no)
# When delivering to an alias "aliasname" that has an
# "owner-aliasname" companion alias, set the envelope
# sender address to the expansion of the
# "owner-aliasname" alias.
#
# propagate_unmatched_extensions (canonical, virtual)
# What address lookup tables copy an address exten-
# sion from the lookup key to the lookup result.
#
# owner_request_special (yes)
# Enable special treatment for owner-listname entries
# in the aliases(5) file, and don't split owner-list-
# name and listname-request address localparts when
# the recipient_delimiter is set to "-".
#
# recipient_delimiter (empty)
# The set of characters that can separate a user name
# from its extension (example: user+foo), or a .for-
# ward file name from its extension (example: .for-
# ward+foo).
#
# Available in Postfix version 2.3 and later:
#
# frozen_delivered_to (yes)
# Update the local(8) delivery agent's idea of the
# Delivered-To: address (see prepend_deliv-
# ered_header) only once, at the start of a delivery
# attempt; do not update the Delivered-To: address
# while expanding aliases or .forward files.
