You probably missed a lot of good mail by doing that. I monitored my  
mail for one month at approx 300-400 messages per day and 100% of mail  
sent using The Bat was spam. Of course, every mail user's pattern is  
different which is why Spamassassin and Bogofilter need individual  
training to work effectively.
