One other thing to do. In ~/.spamassassin/user_prefs, add the line: score MICROSOFT_EXECUTABLE 5.0 That will take care of the MS executables that are contained in incoming e-mails and force the score to 5, which is the default threshold for spam. Once I added that, it eliminated most of the virus/worm crap. I have an evolution filter that deletes those messages specifically, whereas the others I move to a spam folder for subsequent review.
