I use Bayes for site-wide and love it. I have a recipe in my Procmail to grab any message that scores between 6 and 10, and store it in a "suspect" MBOX. Once a week I look through this for false positives and move to a "ConfirmedHam" MBOX, and move the rest to "ConfirmedSPAM" MBOX. I look at the false positives to see why they got caught. Since I'm sitewide, I'd rather let through a few SPAMs than any false positives.
I run Bayes, RBLs, and DCC. I use a threshold of 6.5, as this gives a 0.01% FP rate. I run this on a machine with an 800MHz CPU, RH7.3, 384MB RAM. With Postfix and John Hardin's Sanitizer script for Procmail. I run SA through Procmail. My daily processing stats are: Total number of emails processed by the spam filter : 43724 Number of spams : 29792 ( 68.14%) Number of clean messages : 13932 ( 31.86%) Average message analysis time : 4.08 seconds Average spam analysis time : 3.74 seconds Average clean message analysis time : 4.70 seconds Average message score : 12.38 Average spam score : 21.93 Average clean message score : -5.08 Never have a performance problem My users are very sensitive to P0rn and V1agra ads, so I've jacked these values up at the risk of catching foul real messages. We're a company, so that's not a problem. As a question for the original poster, why not build a corpus and run the GA scoring engine yourself? That's what I'm working on now to improve my local, real world scores. No more guesswork. I will know the rules with little FP, and can crank them up. <<Dan>> | -----Original Message----- | From: Terry Milnes [mailto:[EMAIL PROTECTED] | Sent: Tuesday, November 11, 2003 7:08 AM | To: David B Funk | Cc: [EMAIL PROTECTED] | Subject: Re: [SAtalk] scoring system and values... | | I have been considering using the bayes site wide, however I | have seen a lot of opinions that oppose its use this way. | Furthermore I did/do have doubts as to how well it would work. | ------------------------------------------------------- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.
