If you think about it like this though, that the 'speech' in the Bayes poison is NOTHING like the way people write email. Sure it can be text out of books, but no one writes emails that way. In my experience there is a LOT of net slang and contractions that are NEVER seen in spam. I've only trained about 8000 spam and 6000 ham and my Bayes is VERY, VERY effective.

But remember, the strength of SA is not Bayes alone, but the sum of the parts. If Bayes scores are low, then Razor is there as are the RBLs, evilnumbers and other specialized rulesets. In my opinion, the game is on our side. Look at how the spammers are so desperate that they have to go to GREAT lengths to try to obfuscate the actual in such a way that it is EASILY ignored as nonsense by the average person.

This type of obfuscation greatly reduces a spammers effective return on spam delivered... in other words, even if it is delivered, its as though it wasn't because it is so poorly readable!

When I first started using SA a long time ago, I really missed this significance. I elected not to install Razor then. But man, I LIKE having multiple options. Its GREAT that there are so many RBL's out there. I'm considering going to the trouble of adding Pyzor AND even DCC as well,

The MORE ways that a spammer can get caught, the better!

I'm not saying Bayes isn't working most of the time, but it does seem possible to craft sentences that skew it strongly towards ham. The faked sentences in the original posting contained plenty of hammish words, but there were a few that would eventually end up as spam markers with training. For example, the improperly hyphenated "calms-down" and "stands-still", as well as "caw" and "binocycles".
