m having a problem that are a little similar to one reported earlier today but not quite the same. After seeing a strange-looking false positive, I realized that there were no Bayes scores that would have offset the high score from the rulesets. I did a count on my MailScanner logs and found that 1/3 of the messages labeled as spam had no Bayes scores. Bayes is working fine otherwise. I'm running SpamAssassin 2.63 with MailScanner 4.29.7 (soon to be 4.30). Any idea what's happening here? Thanks in advance.
Lack of bayes score isn't abnormal. Normally it's a sign your bayes training is lacking.
If there is nearly and exact 50/50 probability of spam ( between 49.99% and 50.01%), or if there are no token hits at all, no bayes score will be reported by SA.
However it's a bit unusual to have 1/3 of your messages not hit bayes at all, unless your training is VERY deficient. How often do you train manually? What do the stats look like if you do a sa-learn --dump magic?
