pcre_table
PCRE_TABLE(5) File Formats Manual PCRE_TABLE(5)
NAME
pcre_table - format of Postfix PCRE tables
SYNOPSIS
pcre:/etc/postfix/filename
DESCRIPTION
The Postfix mail system uses optional tables for address rewriting or mail routing. These tables are usually in dbm or db format. Alterna-
tively, lookup tables can be specified in Perl Compatible Regular Expression form.
To find out what types of lookup tables your Postfix system supports use the postconf -m command.
The general form of a PCRE table is:
pattern result
When pattern matches a search string, use the corresponding result.
blank lines and comments
Empty lines and whitespace-only lines are ignored, as are lines whose first non-whitespace character is a `#'.
multi-line text
A logical line starts with non-whitespace text. A line that starts with whitespace continues a logical line.
Each pattern is a perl-like regular expression. 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 sup-
ported, but the only other useful one is `U', which makes matching ungreedy (see PCRE documentation and source for more info).
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 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 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 the conventional perl syntax ($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.
EXAMPLE SMTPD ACCESS MAP
# Protect your outgoing majordomo exploders
/^(?!owner-)(.*)-outgoing@/ 550 Use ${1}@${2} instead
# Bounce friend@whatever, except when whatever is our domain (you would
# be better just bouncing all friend@ mail - this is just an example).
/^friend@(?!my.domain)/ 550 Stick this in your pipe $0
# A multi-line entry. The text is sent as one line.
#
/^noddy@my.domain$/
550 This user is a funny one. You really don't want to send mail to
them as it only makes their head spin.
EXAMPLE HEADER FILTER MAP
/^Subject: make money fast/ REJECT
/^To: friend@public.com/ REJECT
