Speaking of spam and filtering and sa-learn, has anyone else noticed
a marked drop in SpamAssassin's accuracy going from v2.6 to 3.0?
I don't really have the figures to quantify it, but both at work
and at home, with bayes filtering, auto-learning and feeding
the messages with score>5 back into sa-learn, the number of spams
getting through to my inbox has increased, with no noticeable
increase in the number of correct hits.
I rebuilt the bayes DBs as described in the docs when I was upgrading
to 3.0. Since then, I've also tried completely wiping the bayes
files and re-learning a few thousand hams and spams. That didn't
make any noticeable difference.
Many of the false negatives have the same subject lines over
and over. Isn't SpamAssassin supposed to eventually learn
that "*cum*dribble*shot*", for example, is probably spam?
