Lately I've noticed that there seems to be more spam than usual creeping through our SpamAssassin installation. I looked @ the message headers, and I've noticed that on most of the ones that are getting through, I'm seeing this:
BAYES_00 -4.90
What does that mean? Do I have an improperly trained Bayes Database somehow?
Generally, yes... You definitely should not be hitting BAYES_00 on spam. Looking at my most recent 200 spams, the lowest any of them scored is BAYES_44.
Is there a way that I can tell SA to reset this one Bayes rule?
No.. Not in any practical way at least. Bayes isn't directly rule based...
Bayes generates a spam-probability percentage from 0 to 99. BAYES_00 means that the bayes calculation resulted in less than 1% probability of spam. The way to reset the bayes calculation is to reset the entire bayes database.
You could change the score of BAYES_00, but that's covering up the effects, and not solving the problem.. you've got a poorly trained bayes database.
