That is, they don't correct for the fact that enlarge and p...s frequently occur together, and sum the probabilities. To do it right is hard. I used to run a "Bayesian" filter at work, until they disabled Unix e-mail at the end of October, and it worked fairly well. At home I run a homebrew. First I run a whitelist of known good addresses, then I look for e-mail lists, then spamassassin, and then I run my UniqIP filter. I keep a little database of every IP I have seen in the handoff to my ISPs, and if I have never seen it before, I drop it into a special folder. I also note spam IP's in the database as well. About 95% of my spam currently comes from unique IP's. Apparently the blacklists are effective enough that the big time spammers now use a "Hedy Lamar" style multiplexing technology, and blast small loads from many compromised systems. I'm also working on a spam detector utilizing DNA sequencing technology. Seriously! -- ----------------------------------------------------------------------- | Alan K.
