The best thing to do is probably throw the current database away and start over. As you seem to have several users, you should have bayes working again within a very few hours, or less.
You should delete the current database, reset the scores to normal (and increase the bayes_99 score to something around 4 if you aren't using 3.0.4), and then manually train Bayes on a few hundred known ham and spam before letting autolearning take over. The other thing you should do is decrease bayes autolearn ham threshold to 0 or even -.1 or so. By default it is too high, and will far too often lead to bayes poisioning if the state of the database isn't watched carefully. You may also want to take the bayes autolearn spam threshold up to a higher value than it has by default; although this usually isn't required. Loren
