Sure it is. Bayes will autolearn messages right from the start. It just waits until it has seen 200 ham and 200 spam before it starts contributing to the score. There is nothing saying that you have to manually learn the first group of messages. On the other hand, since there is very little direct feedback from that initial set of messages, you have to be careful that false positives and negatives do not corrupt the database before you even get started. > > It seems to me that Bayes is highly sensitive to the types of ham > > and spam that each user gets.
