I'm going to ask a really silly question... First, my particulars: Fedora Core 8 x86_64 Qmail 1.03 (Running a Modified QmailRocks configuration, which is everything except vpopmail) Qscan ClamAV SpamAssassin 3.2.4
I periodically audit messages that get through SpamAssassin to see why they didn't reach the score threshold (mine is set at 3.5). I compare the messages with the scoring details that get logged in "maillog". I noticed that in many of the messages that got through were hitting the BAYES_00 through BAYES_40 rules. I looked at the rules page, and the scores for those rules are negative (ranging from -2.599 (eek!) to -0.185). When you get to BAYES_50 and higher, the scores turn positive. Also, in many instances, the negative BAYES_* scores made the difference between reaching the threshold and not. My question is WHY are those rules negative? I went ahead and assigned a positive score for those rules (ranging from 0.001 to 0.040), but I figured I had better ask here why those scores are negative. I'm figuring there's a good reason, and I don't want to shoot myself in the foot.
