# 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. However, the message header filter has
|
|
# no knowledge of MIME headers that are embedded 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).
|
|
#
|
|
# The second field is the "replacement" string - the text
|
|
# returned by the match.
|
|
#
|
|
# REJECT The entire message is rejected.
|
|
# REJECT text.... The text is sent to the originator.
|
|
# IGNORE The header line is silently discarded.
|
|
# WARN The header is logged (not rejected) with a warning.
|
|
# WARN text.... As above, and the text is logged, too.
|
|
#
|
|
# 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!)

/^Subject: Make Money Fast/ REJECT
