It is, but I won't tell you because it wouldn't do you any good! :-) For the Bayesian filter to be accurate, it has to be your spam and your ham. True, everybody's spam is quite similar, but there are differences, and it is not unlikely that it would make very skewed statistics, and would be of little use. Another point to emphasize is that it is equally important to train it with your own ham as it is to train it with your own spam, and in roughly equal numbers. So, I would strongly recommend you just manually save the spam to a folder for some time now, and build your spam database from there. Basically, what I did to train it, was to take about 2000 old spams I had gather a long time ago, when I was actively whacking spammers, then used 1000 recent spams from my old account (that took me just a week to gather ! :-( ). Then, on the top of that, I fed it with 250 spams from my new account. Nowadays, I feed it mainly with false negatives. The problem with this approach, is that the character of spam has changed substantially since I gathered those 2000, but it works apparently quite good for me anyway. Finally, I have a few spamtraps (hehe, spambots, do your worst: href="mailto:[EMAIL PROTECTED]"), which I intend to use to train it automatically, once I've got my Exim4 server configured right! Then, I took all the legitimate mail from the saved folders at my old account, and fed it to the learner as ham. Then, I took a lot of recent list mail and fed it too. Nowadays I reguralily supply it with most of that which lands in my inbox, that is, mail that is directed to me personally. It has made the Bayesian filter very accurate, but it has, as you can tell, taken a lot of effort.
