Personally I have run into perhaps 4 false positives with 15,000 SPAM messages caught. Over time I learned more about how SpamAssassin works and adjusted my spam settings to a high spam threshold, meaning the likelihood of false positives is far lower but some spam does make it through the filter. However, when I added Vipul's Razor version 2 to SpamAssassin's checks, that eliminated almost all of these spam leaks too. SpamAssassin makes use of pattern matching, open relay blacklists and Vipul's Razor in calculating the likelihood of a message being spam or not. While pattern matching is subject to occasional errors, blacklists and Vipul's Razor should NEVER have a false positive, you may consider using those two instead. I personally trust that a combination of the three works very well after configuration. I have something like 99.99% effective spam filtering now, with no false positives for several weeks. (I read through my entire SPAM folder periodically, just to make sure.) Warren
