Why do you not pre-train the Bayesian filter?

The reason for this is that each bayesian filter will adapt to the type of SPAM which that particular mail server receives. This means that pre-training a filter is impossible as it will only result in inaccurate detection. Also, a pre-trained filter would mean that almost all installations of Ability Mail Server would be protected by the same filter, and so making it easier for spammers to adopt their mail to appear as non-SPAM.
