Increasing spam filtering with spamassassin

Nikolaos,
First question I have how many ham/spam have you used to train the bayes. Need at least 200 of each for it to even start working. Also, BAYES_00=-1.9 score usually points to poor training of the bayes database. Basically it means that the those spam messages look a lot what spamasassin has been told are ham messages.
How are you training the database?
