Indeed. Deleting spamcaught messages without any tracking system is
asking for trouble.

In my new Python/qmail solution, I simply log the results to a file
which gives an indication of what the messages is and why:
2002/08/19 16:51:38 -8 | "Free Copy of your Credit Report": ""
port at overlycute.com> | insist[RECIPIENTS/<somebody at whatever\.com>];
(remove|unsubsc?ribe)]; bad[BODY/click (reply|here|now)];
\b]; bad[BODY/e-?mail market(er|ing)]; bad[SENDER/free];
bad[subject/credit (bureau|report)]; bad[subject/your credit]
Then I just tail -f | cut -b -79 the file and glance at the xterm
occasionally. So far I've gotten very few false positives with the new
system; the prior system, using procmailsc, had trouble with accounting
since I couldn't really tell which of the rules matched and why.
