my girlfriend has been bitching at me for quite some time now to figure out why spamassassin isn't catching the spam like it used to. I'm using 3.0.2 on a debian woody box. Its from www.backports.org (great site). Here is an example of the X-Virus/Spam headers from a spam that was caught:
Your bayes database looked to be reasonably trained. The false-negative was labeled 99% spam by Bayes.
I don't see any RBL checks, which might have made the difference on this one, if it's already been seen and flagged. Do you have Net::DNS installed and the RLB tests enabled? What happens if you feed it through spamassassin with the -D flag?
