# 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 to
# create an indexed file for fast lookup.
#
# Execute the command "postmap /etc/postfix/relocated" to
# rebuild a default-type indexed file after changing the
# text file, or execute "postmap type:/etc/postfix/relo-
# cated" to specify an explicit type.
#
# The default indexed file type is configured with the
# default_database_type parameter. Depending on the platform
# this may be one of lmdb:, cdb:, hash:, or dbm: (without
# the trailing ':').
#
# When the table is provided via other means such as NIS,
# LDAP or SQL, the same lookups are done as for ordinary
# indexed files. Managing such databases is outside the
# scope of Postfix.
#
# 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 a 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
# o By default, Postfix will prepend a hard-coded pre-
# fix "5.1.6 User has moved to " to a table lookup
# result, and the format for a table entry is as fol-
# lows:
#
# pattern new_location
#
# Where new_location specifies contact information
# such as an email address, or perhaps a street
# address or telephone number.
#
# o Postfix 3.11 and later can optionally disable the
# hard-coded prefix. Specify "relocated_prefix_enable
# = no" in main.cf, and specify relocated_maps
# entries with your own RFC 3463-compliant enhanced
# status code and text, for example:
#
# pattern 5.1.6 Mailbox has moved to user@example
# pattern 5.2.0 Mailbox is unavailable
# pattern 5.2.1 Mailbox is disabled
#
# 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 available in Postfix 2.5 and later.
#
# 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, $2 and so on.
#
# TCP-BASED TABLES
# This section describes how the table lookups change when
# lookups are directed to a TCP-based server. For a descrip-
# tion of the TCP client/server lookup protocol, see tcp_ta-
# ble(5). This feature is available in Postfix 2.5 and
# later.
#
# Each lookup operation uses the entire address once. Thus,
# user@domain mail addresses are not broken up into their
# user and @domain constituent parts, nor is user+foo broken
# up into user and foo.
#
# Results are the same as with indexed file lookups.
#
# BUGS
# The table format does not understand quoting conventions.
#
# CONFIGURATION PARAMETERS
# The following main.cf parameters are especially relevant.
# The text below provides only a parameter summary. See
# postconf(5) for more details including examples.
#
# relocated_maps (empty)
# Optional lookup tables with new contact information
# for users or domains that no longer exist.
#
# Available with Postfix version 3.11 and later:
#
# relocated_prefix_enable (yes)
# Prepend the prefix "5.1.6 User has moved to " to
# all relocated_maps lookup results.
#
# Other parameters of interest:
#
# inet_interfaces (all)
# The local network interface addresses that this
# mail system receives mail on.
#
# mydestination ($myhostname, localhost.$mydomain, local-
# host)
# The list of domains that are delivered via the
# $local_transport mail delivery transport.
#
# myorigin ($myhostname)
# The domain name that locally-posted mail appears to
# come from, and that locally posted mail is deliv-
# ered to.
#
# proxy_interfaces (empty)
# The remote network interface addresses that this
# mail system receives mail on by way of a proxy or
# network address translation unit.
