# NAME
|
|
# canonical 5
|
|
# SUMMARY
|
|
# format of Postfix canonical table
|
|
# SYNOPSIS
|
|
# \fBpostmap /etc/postfix/canonical\fR
|
|
#
|
|
# \fBpostmap -q "\fIstring\fB" /etc/postfix/canonical\fR
|
|
#
|
|
# \fBpostmap -q - /etc/postfix/canonical <\fIinputfile\fR
|
|
# DESCRIPTION
|
|
# The optional \fBcanonical\fR table specifies an address mapping for
|
|
# local and non-local addresses. The mapping is used by the
|
|
# \fBcleanup\fR(8) daemon. The address mapping is recursive.
|
|
#
|
|
# Normally, the \fBcanonical\fR 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/canonical\fR 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 expressions. In that case,
|
|
# the lookups are done in a slightly different way as described below.
|
|
#
|
|
# The \fBcanonical\fR 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). Think Sendmail rule set \fBS3\fR, if you like.
|
|
#
|
|
# Typically, one would use the \fBcanonical\fR table to replace login
|
|
# names by \fIFirstname.Lastname\fR, or to clean up addresses produced
|
|
# by legacy mail systems.
|
|
#
|
|
# The \fBcanonical\fR mapping is not to be confused with \fIvirtual
|
|
# domain\fR support. Use the \fBvirtual\fR(5) map for that purpose.
|
|
#
|
|
# The \fBcanonical\fR mapping is not to be confused with local aliasing.
|
|
# Use the \fBaliases\fR(5) map for that purpose.
|
|
# TABLE FORMAT
|
|
# .ad
|
|
# .fi
|
|
# The format of the \fBcanonical\fR table is as follows:
|
|
# .IP "\fIpattern result\fR"
|
|
# When \fIpattern\fR matches a mail address, replace it by the
|
|
# corresponding \fIresult\fR.
|
|
# .IP "blank lines and comments"
|
|
# Empty lines and whitespace-only lines are ignored, as
|
|
# are lines whose first non-whitespace character is a `#'.
|
|
# .IP "multi-line text"
|
|
# A logical line starts with non-whitespace text. A line that
|
|
# starts with whitespace continues a logical line.
|
|
# .PP
|
|
# 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 address\fR"
|
|
# \fIuser\fR@\fIdomain\fR is replaced by \fIaddress\fR. This form
|
|
# has the highest precedence.
|
|
# .sp
|
|
# This is useful to clean up addresses produced by legacy mail systems.
|
|
# It can also be used to produce \fIFirstname.Lastname\fR style
|
|
# addresses, but see below for a simpler solution.
|
|
# .IP "\fIuser address\fR"
|
|
# \fIuser\fR@\fIsite\fR is replaced by \fIaddress\fR when \fIsite\fR is
|
|
# equal to $\fBmyorigin\fR, when \fIsite\fR is listed in
|
|
# $\fBmydestination\fR, or when it is listed in $\fBinet_interfaces\fR.
|
|
# .sp
|
|
# This form is useful for replacing login names by
|
|
# \fIFirstname.Lastname\fR.
|
|
# .IP "@\fIdomain address\fR"
|
|
# Every address in \fIdomain\fR is replaced by \fIaddress\fR.
|
|
# This form has the lowest precedence.
|
|
# .PP
|
|
# In all the above forms, when \fIaddress\fR has the form
|
|
# @\fIotherdomain\fR, the result is the same user in \fIotherdomain\fR.
|
|
# 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. An unmatched address extension
|
|
# (\fI+foo\fR) is propagated to the result of table lookup.
|
|
# REGULAR EXPRESSION TABLES
|
|
# .ad
|
|
# .fi
|
|
# 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 \fBregexp_table\fR(5)
|
|
# or \fBpcre_table\fR(5).
|
|
#
|
|
# 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.
|
|
# BUGS
|
|
# The table format does not understand quoting conventions.
