Are there any BAYES hits on their messages, ham or spam? BAYES_{not 50} would be a positive confirmation. I'm not sure offhand if BAYES_50 hits when bayes is enabled but insufficiently trained...
In one email, I'm seeing this: 3.0 BAYES_95 BODY: Bayes spam probability is 95 to 99%So I guess it's working. It looks like it got scored +3 points for having a greater than 95% probability of being spam according to the Bayes algorithm.
