Hi Fritz, I did that temporarily but started getting false positives so I set it back. Not sure why that is, spot checks on the spam and notspam folders show that the messages are being classified correctly. RebuildSpamDB is the latest version and appears to be running correctly as evidenced by the timestamps on spamdb, spamdb.helo, and even rebuildrun.txt, although rebuildrun.txt is empty despite permissions being set correctly.
Many of the false positives appear to score zero for the confidence but they still score the full amount of baysValencePB or close to it. The whole Bayesian confidence mechanism makes no sense to me, if the two were multiplied or the confidence value was subtracted when confidence was low then that would seem to be more effective. Why would you penalize a message by the full value of baysValencePB when you have zero confidence that it's spam? I'll admit that I've never been that impressed with ASSP's Bayesian functionality despite the fact that in every other respect nothing I've seen approaches the effectiveness of ASSP. The best Bayesian filter I've encountered is SpamBayes, another open-source project. I've often wished that ASSP would integrate SpamBayes for its Bayesian filtering but I digress. I'll do some additional spot-checking on the Bayesian folders to see if I can find mis-classified messages but I doubt that's the problem since ASSP has been extremely accurate in classifying messages so far. False-positives have pretty much always been due to a problem at the sender's end and almost zero spam got through before the spammers started pulling the no DNS response trick. It's strange to see spam making it into my inbox again. - Phil -- View this message in context: http://anti-spam-smtp-proxy-server.996265.n3.nabble.com/PTR-reverse-lookup-failure-letting-spam-get-through-tp38017p38053.html Sent from the assp-user mailing list archive at Nabble.com. ------------------------------------------------------------------------------ WatchGuard Dimension instantly turns raw network data into actionable security intelligence.
