|
|
# Sample pcre (PERL-compatible regular expression) map file for
|
|
# message header filtering. See pcre_table(5) for syntax description.
|
|
#
|
|
# Message headers are filtered one at a time. This filter understands
|
|
# multi-line message headers, including MIME headers in the message
|
|
# body.
|
|
#
|
|
# 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-INsensitive, 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).
|
|
#
|
|
# A block of table entries may be "enclosed" by a line with
|
|
# `if /pattern/flags' and a line with `endif'. This causes
|
|
# the block of table entries to be examined only when the
|
|
# pattern produces a successful match. The `if..endif' may
|
|
# be nested. There currently is no `else' operator.
|
|
#
|
|
# The second field is the "replacement" string - the text
|
|
# returned by the match.
|
|
#
|
|
# REJECT [optional text...]
|
|
# Reject the entire message. The optional text is sent to
|
|
# the originator and is logged to the maillog file.
|
|
# IGNORE Silently ignore the message header.
|
|
# WARN [optional text...]
|
|
# Log the message header and the optional text. This is
|
|
# useful for testing. When the pattern is OK, change the
|
|
# WARN into a REJECT or into a DISCARD.
|
|
# HOLD [optional text...]
|
|
# Place the message on the hold queue. Mail on hold can
|
|
# be inspected with the postcat command, and can be
|
|
# destroyed or taken off hold (i.e. delivered) with the
|
|
# postsuper command. The matched header is logged
|
|
# together with the optional text.
|
|
# DISCARD [optional text...]
|
|
# Claim successful delivery and silently discard the
|
|
# message. The matched header is logged together with
|
|
# the optional text.
|
|
# FILTER transport:nexthop
|
|
# After the message is queued, send the entire
|
|
# message through a content filter. This
|
|
# requires different cleanup servers before
|
|
# and after the filter, with header/body
|
|
# checks turned off in the second cleanup
|
|
# server. More information about content filters
|
|
# is in the Postfix FILTER_README file. This feature
|
|
# overrides the main.cf content_filter setting.
|
|
#
|
|
# 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!)
