Please keep list traffic on the list.

The default filter installed with MIMEDefang only tags messages over the
"required_score" value in sa-mimedefang.cf.  To change that behavior, you'll
need to modify the filter.  Common practice is to tag above one threshold and
reject above another.  The section of your filter to look at is below:


    # Spam checks if SpamAssassin is installed
    if ($Features{"SpamAssassin"}) {
        if (-s "./INPUTMSG" < 100*1024) {
            # Only scan messages smaller than 100kB.  Larger messages
            # are extremely unlikely to be spam, and SpamAssassin is
            # dreadfully slow on very large messages.
            my($hits, $req, $names, $report) = spam_assassin_check();
            my($score);
            if ($hits < 40) {
                $score = "*" x int($hits);
            } else {
                $score = "*" x 40;


To reject above 10, modify the filter as so:

# Spam checks if SpamAssassin is installed
    if ($Features{"SpamAssassin"}) {
        if (-s "./INPUTMSG" < 100*1024) {
            # Only scan messages smaller than 100kB.  Larger messages
            # are extremely unlikely to be spam, and SpamAssassin is
            # dreadfully slow on very large messages.
            my($hits, $req, $names, $report) = spam_assassin_check();
            my($score);

            if ($hits >= 10) {
				md_graphdefang_log('spam', $hits, $RelayAddr);
                        action_bounce('Message appears to be Spam.');
                            }
            else {

            if ($hits < 40) {
                $score = "*" x int($hits);
            } else {
                $score = "*" x 40;
