I'm running SA 3.2.1 with Postfix, routing mail to it through spamd/spamc. I have a site-wide Bayesian database that I trained some time ago with a few hundred hams, and then since then I've trained spam into it anytime I received a false negative. With the recent influx of PDF and stock spam, I've been updating rules and tweaking settings to get SA to catch them. I noticed something interesting - all the spam I've gotten in at least the last few days has scored 0 on Bayes. That's causing SA to drop the message's score by 2.6 points, throwing other filters off-balance, so to speak. I'm wondering if this is happening because I've been dutifully teaching these stock spam messages into the database. They're full of nonsense words, and although I think I've been told on this list that it's ok to submit them, it seems like that could reduce the Bayes reliability. Or, maybe I just need to refresh the database with a slew of new ham messages.
Attached is a spam I got today, which got good hits in other tests but 0 probability in Bayes. Any suggestions on how to remedy this would be appreciated.
