Dean,

Based on the error, I would guess you placed the new lines BEFORE the lines
that call SpamAssassin (and therefore, BEFORE the variable "$hits" gets
defined.  (Your error said that one side of the ">=" comparison was not
initialized.)

Make sure the added lines appear AFTER the call to SpamAssassin, so that
SpamAssassin can get a chance to set the value of $hits.

Look for this series of lines in mimedefang-filter...

            # 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 >= $req) {
                md_graphdefang_log('spam', $hits, $RelayAddr);
                my($score);
                if ($hits < 40) {
                    $score = "*" x int($hits);
                } else {
                    $score = "*" x 40;
                }

Then add your lines immediately after that.
