Hi, I have configured Baysian filter for many months, and now past 5000 messages learning curve. I have yet to see filter stop a single spam message. Can anyone share how we can all improve Baysian filter? I have tried lowering triger point to 77% the other day and spam never detected. i have enabled reporting and see activity reported so it works i imagine. I am concerned that Baysian filter does take lot CPU time and no results!!! Is algorithm weak? or are we doing something wrong? Any comments welcomed Alex99

Alex99,
Please note that the Bayesian filter is the last filter to be used to detect spam. It's used only after all the other filters have tried to test the email from spam. As such, it is less likely to find spam than all the other filters, since most of it will have been stopped already. Can you try running the following query on the database? It returns a list of how many emails in the quarantine have been blocked by the various rules SELECT tblQuarantine.RejectID, tblRejectCodes.RejectDesc, COUNT(tblQuarantine.RejectID) AS Total FROM tblQuarantine INNER JOIN tblRejectCodes ON tblQuarantine.RejectID = tblRejectCodes.RejectID GROUP BY tblQuarantine.RejectID, tblRejectCodes.RejectDesc As a comparison, this is what our own stats look right now for our mailserver: 57819 IP found in MAPS search 19328 IP address is from a blacklisted country 9189 URL in email found in SURBL search 6204 Invalid sender domain MX record 4803 SPF Sender Policy Framework match 1165 Keywords found in content 1154 Exceeded maximum number of RCPT TO 721 Mail From and Mail To domains are equal 397 Virus Found in email 281 IP blocked by honeypot entry 168 Statistical filter match 4 Domain is in local blacklist file 2 Mail From and Mail To are equal Edited by LogSat |

Since I see posts from other people who can't have the bayes filter to kick in, I would just notice that I'm still not able to, too. Here's my report after a complete db reset some weeks ago on a 2.5.1.441 running on NT server and MS Sql RejectID,RejectDesc,Total Ciao
