# Sample pcre (PERL-compatible regular expression) map file
#
# The first field is a perl-like regular expression. The expression
# delimiter can be any character except whitespace, or characters
# that have special meaning to the regexp library (traditionally
# the forward slash is used). The regular expression can contain
# whitespace.
#
# By default, matching is case-INsensative, although following
# the second slash with an 'i' will reverse this. Other flags are
# supported, but the only other useful one is 'U', which makes
# matching ungreedy (see PCRE documentation and source for more
# info).
#
# The second field is the "replacement" string - the text
# returned by the match. When used for smtpd checks, this would
# be a helpful message to misguided users (or an offensive
# message to spammers), although it could also be a domain name
# or other data for use as a transport, virtual, or other map.
#
# Substitution of sub-strings from the matched expression is
# possible using the conventional perl syntax. The macros in the
# replacement string may need to be protected with curly braces
# if they aren't followed by whitespace (see the examples
# below).
#
# Lines starting with whitespace are continuation lines - they are
# appended to the previous line (there should be no whitespace
# before your regular expression!)
#
# This code was originally developed for SPAM control. However
# it seems that it can be used equally well for address rewriting
# by virtual or canonical lookups. Using this for aliases might
# be stretching things, though.
#
# Protect your outgoing majordomo exploders

/^(?!owner-)(.*)-outgoing@(connect.com.au)$/ 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@(?!connect.com.au).*$/ 550 Stick this in your pipe $0
# A multi-line response

/^noddy@connect.com.au$/
550 This user is a funny one. You really don't want to send mail to them
as it only makes their head spin.
