bayes_min_ham_num 200 bayes_min_spam_num 200 Bayes won't run until you have learned at least 200 each of spam and ham. So you normally won't expect it to work for the first day or so after you turn it on.
Once it is running, you should start seeing rule hits in your mails like BAYES_00 (for ham) or BAYES_99 (for spam). There are other rules, but they all start with BAYES_??. I'm a little concerned with your bayes ham learning threshold, it seems a little high to me. You moght consider taking it down to .2 or .1 or so. Many people like having it near -.1. You can also run spamassassin -D <mail.msg and look at the debug output. It will tell you quite a lot about what Bayes is doing, if anything. Loren
