# NAME

# relocated 5
|
|
# SUMMARY
|
|
# Postfix relocated table format
|
|
# SYNOPSIS
|
|
# \fBpostmap /etc/postfix/relocated\fR
|
|
# DESCRIPTION
|
|
# The optional \fBrelocated\fR(5) table provides the information that is
|
|
# used in "user has moved to \fInew_location\fR" bounce messages.
|
|
#
|
|
# Normally, the \fBrelocated\fR(5) table is specified as a text file
|
|
# that serves as input to the \fBpostmap\fR(1) command.
|
|
# The result, an indexed file in \fBdbm\fR or \fBdb\fR format,
|
|
# is used for fast searching by the mail system. Execute the command
|
|
# "\fBpostmap /etc/postfix/relocated\fR" 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 expressions, 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.
|
|
# CASE FOLDING
|
|
# .ad
|
|
# .fi
|
|
# 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
|
|
# .ad
|
|
# .fi
|
|
# The input format for the \fBpostmap\fR(1) command is as follows:
|
|
# .IP \(bu
|
|
# An entry has one of the following form:
|
|
# .ti +5
|
|
# \fIpattern new_location\fR
|
|
# .br
|
|
# Where \fInew_location\fR specifies contact information such as
|
|
# an email address, or perhaps a street address or telephone number.
|
|
# .IP \(bu
|
|
# Empty lines and whitespace-only lines are ignored, as
|
|
# are lines whose first non-whitespace character is a `#'.
|
|
# .IP \(bu
|
|
# A logical line starts with non-whitespace text. A line that
|
|
# starts with whitespace continues a logical line.
|
|
# TABLE SEARCH ORDER
|
|
# .ad
|
|
# .fi
|
|
# 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:
|
|
# .IP \fIuser\fR@\fIdomain\fR
|
|
# Matches \fIuser\fR@\fIdomain\fR. This form has precedence over all
|
|
# other forms.
|
|
# .IP \fIuser\fR
|
|
# Matches \fIuser\fR@\fIsite\fR when \fIsite\fR is $\fBmyorigin\fR,
|
|
# when \fIsite\fR is listed in $\fBmydestination\fR, or when \fIsite\fR
|
|
# is listed in $\fBinet_interfaces\fR or $\fBproxy_interfaces\fR.
|
|
# .IP @\fIdomain\fR
|
|
# Matches other addresses in \fIdomain\fR. This form has the lowest
|
|
# precedence.
|
|
# ADDRESS EXTENSION
|
|
# .fi
|
|
# .ad
|
|
# When a mail address localpart contains the optional recipient delimiter
|
|
# (e.g., \fIuser+foo\fR@\fIdomain\fR), the lookup order becomes:
|
|
# \fIuser+foo\fR@\fIdomain\fR, \fIuser\fR@\fIdomain\fR, \fIuser+foo\fR,
|
|
# \fIuser\fR, and @\fIdomain\fR.
|
|
# REGULAR EXPRESSION TABLES
|
|
# .ad
|
|
# .fi
|
|
# 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 \fBregexp_table\fR(5) or
|
|
# \fBpcre_table\fR(5). For a description of the TCP client/server
|
|
# table lookup protocol, see \fBtcp_table\fR(5).
|
|
# This feature is not available up to and including Postfix version 2.3.
|
|
#
|
|
# Each pattern is a regular expression that is applied to the entire
|
|
# address being looked up. Thus, \fIuser@domain\fR mail addresses are not
|
|
# broken up into their \fIuser\fR and \fI@domain\fR constituent parts,
|
|
# nor is \fIuser+foo\fR broken up into \fIuser\fR and \fIfoo\fR.
|
|
#
|
|
# 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 \fB$1\fR, \fB$2\fR and so on.
|
|
# TCP-BASED TABLES
|
|
# .ad
|
|
# .fi
|
|
# This section describes how the table lookups change when lookups
|
|
# are directed to a TCP-based server. For a description of the TCP
|
|
# client/server lookup protocol, see \fBtcp_table\fR(5).
|
|
# This feature is not available up to and including Postfix version 2.3.
|
|
#
|
|
# Each lookup operation uses the entire address once. Thus,
|
|
# \fIuser@domain\fR mail addresses are not broken up into their
|
|
# \fIuser\fR and \fI@domain\fR constituent parts, nor is
|
|
# \fIuser+foo\fR broken up into \fIuser\fR and \fIfoo\fR.
|
|
#
|
|
# Results are the same as with indexed file lookups.
|
|
# BUGS
|
|
# The table format does not understand quoting conventions.
