The only real change you'd have to make to the default supplied filter
is to add a check *after* the SpamAssassin call for what you want to
# Spam checks if SpamAssassin is installed
if (-s "./INPUTMSG" < 100*1024)
# Only scan messages smaller than 100kB. Larger messages
# are extremely unlikely to be spam, and SpamAssassin is
# dreadfully slow on very large messages.
my($hits, $req, $names, $report) = spam_assassin_check();
if ($hits < 40)
$score = "*" x int($hits);
$score = "*" x 40;
# adding this "if/else" is the only change you should need
# You can put anything you want in the message, of course
action_notify_administrator("$Sender sent spam with subject $Subject\n");
# We add a header which looks like this:
# X-Spam-Score: 6.8 (******) NAME_OF_TEST,NAME_OF_TEST
# The number of asterisks in parens is the integer part
# of the spam score clamped to a maximum of 40.
# MUA filters can easily be written to trigger on a
# minimum number of asterisks...
if ($hits >= $req)
action_change_header("X-Spam-Score", "$hits ($score) $names");
md_graphdefang_log('spam', $hits, $RelayAddr);
# If you find the SA report useful, add it, I guess...
action_add_part($entity, "text/plain", "-suggest",
# Delete any existing X-Spam-Score header?
