Now, I am not a statistician but I am a mathematician. If my understanding of Bayesian statistics (and if people actually are being accurate when they call this method Bayesian), this shouldn't matter at all - that's the beauty of the process. If the Bayseian analysis actaully takes into account the joint and conditional densities of word frequency, and it has a reasonable way to assign an expectation to them (ie, if the corpus is seeded with real-non spam and real spam), the fact that a spam has been seeded with real words should show up in the joint and conditional frequency analysis. This would allow the filter to assign a spam score, though perhaps with a smaller confidence interval. Of course spammer can get around this by not writing spammy emails, but that's always been (and always will) be a sure-fire way of getting around content-oriented filtering. -- Ross Vandegrift [EMAIL PROTECTED] A Pope has a Water Cannon.
