I ran into the same problem today, and came here looking for a solution. I think it would be a good feature to allow users to disable AWL for certain email addresses specified in the user_prefs file. It would be easy to implement. Can anyone see any downside to doing so? Chris Eykamp At 10:4

2002-11-18 Thread Christopher Eykamp
Hello, I've implemented a Bayesian filtering scheme on my system that runs concurrent with SpamAssassin. It works really well, but I am starting to think there is an easy attack that would render the filtering useless. What if, at the end of every message, spammers appended a list of a thousa

Would it make sense to do a Bayesian analysis using not only on individual words, but also the SpamAssassin regex tests in order to detect phrases and patterns that would be missed using a naive word-by-word analysis? And if that worked, would it then not make sense to discard the standard SA
