# NAME

|
# regexp_table 5
|
|
# SUMMARY
|
|
# format of Postfix regular expression tables
|
|
# SYNOPSIS
|
|
# regexp:/etc/postfix/filename
|
|
# DESCRIPTION
|
|
# The Postfix mail system uses optional tables for address
|
|
# rewriting or mail routing. These tables are usually in
|
|
# \fBdbm\fR or \fBdb\fR format. Alternatively, lookup tables
|
|
# can be specified in POSIX regular expression form.
|
|
#
|
|
# To find out what types of lookup tables your Postfix system
|
|
# supports use the \fBpostconf -m\fR command.
|
|
#
|
|
# The general form of a Postfix regular expression table is:
|
|
# .IP "blanks and comments"
|
|
# Blank lines are ignored, as are lines beginning with `#'.
|
|
# .IP "leading whitespace"
|
|
# Lines that begin with whitespace continue the previous line.
|
|
# .IP "\fIpattern result\fR"
|
|
# When \fIpattern\fR matches a search string, use the corresponding
|
|
# \fIresult\fR. A line that starts with white space continues the
|
|
# preceding line.
|
|
# .IP "\fIpattern1!pattern2 result\fR"
|
|
# Matches \fIpattern1\fR but not \fIpattern2\fR.
|
|
# .PP
|
|
# Each pattern is a regular expression enclosed by a pair of delimiters.
|
|
# The regular expression syntax is described in \fIre_format\fR(7).
|
|
# The expression delimiter can be any character, except whitespace
|
|
# or characters that have special meaning (traditionally the forward
|
|
# slash is used). The regular expression can contain whitespace.
|
|
#
|
|
# By default, matching is case-insensitive, although following
|
|
# the second slash with an `i' flag will reverse this. Other flags
|
|
# are `x' (disable extended expression syntax), and `m' (enable
|
|
# multi-line mode).
|
|
#
|
|
# Each pattern is applied to the entire lookup key string.
|
|
# 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, and
|
|
# \fIuser@domain\fR mail addresses are not broken up into their
|
|
# \fIuser\fR and \fIdomain\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.
|
|
#
|
|
# Substitution of substrings from the matched expression into the result
|
|
# string is possible using $1, $2, etc.. The macros in the result string
|
|
# may need to be written as ${n} or $(n) if they aren't followed
|
|
# by whitespace.
|
|
# EXAMPLES
|
|
# # Disallow sender-specified routing. This is a must if you relay mail
|
|
# # for other domains.
|
|
# /[%!@].*[%!@]/ 550 Sender-specified routing rejected
|
|
#
|
|
# # Postmaster is OK, that way they can talk to us about how to fix
|
|
# # their problem.
|
|
# /^postmaster@.*$/ OK
|
|
#
|
|
# # Protect your outgoing majordomo exploders
|
|
# /^(.*)-outgoing@(.*)$/!/^owner-.*/ 550 Use ${1}@${2} instead
