I keep on reading these concerned postings on so-called "bayes-posion" ... My
personal experience is that *NONE* of these had managed to get through my
well trained bayes database.
Now, I did get one "paris hilton" spam through with BAYES_50 (it contained no
bayes posion). I suspect the spammer actually hand crafted the spam against
his own bayes setup. But all subsequent "paris hilton" spam were caught with
BAYES_99.
That's my 2 cents (cdn) .
