I'm getting more and more spam that seems to be able to avoid the Bayes rules. Typically they contain hundreds of nonsense words at the end. I've gone from a false negative of less than one per 10,000 to where I get 10-15 each night. Has anyone else noticed this? Any suggestions?
I have Bayesian filtering disabled currently, and added a simple custom rule that catches most of these nonsense lines.
body RANDOMLINE_LOWERCASE /([a-z]{4,}\s{1,2}){30,}/
describe RANDOMLINE_LOWERCASE Long line of random words with no interpunction or capitals
I give it a fairly high score as well, something like 2.50, helps to push a lot of my spam over my threshold (5.0) and I haven't seen any false positives because of it.
