I have been running the bayesian filter for several days now and it has yet to catch a single piece of spam. 

I am well past the kick in point as far as volume but don't understand why it isn't doing anything.  All I see is 0% SPAM.

Anyone else seeing this and is there a fix?

Mike,

Did you receive 5,000 spam and 5,000 good emails? The Bayesian filter kicks in after both good and bad count are over 5000. If so, even if your other filters were super-effective, you should see at least a small amonut of emails blocked by the Bayesian filter. Please note that the statistical analysis only occurs after all other filters have failed to catch spam, so the number of emails blocked by the Bayesian filter will be small when compared to others.

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, and post the results?

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

Here is the results of the Query...  One thing: I am not putting all of the rejected mail in the Quarantine.  I started out doing that but the numbers were pretty large. 

Do I need to Quarantine everything for the Filter to work properly? 

RejectCountQ
RejectID RejectDesc Total
2 EmailFrom is in local blacklist file 1
4 Empty Mail From 60
5 Mail From and Mail To are equal 10
6 Mail From and Mail To domains are equal 20
7 Exceeded maximum number of RCPT TO 479
8 IP address is from a blacklisted country 4597
12 IP found in MAPS search 522
13 Keywords found in content 545

Mike,

The numbers appear a little low, even though we can't be sure without knowing how many emails are not being quarantined. As a side note, no, you do not need to quarantine emails for the Bayesian filter to work.

Since the numbers are low, can you please confirm that you have indeed received at least 5,000 good emails, besides 5,000 bad ones? You can verify this by looking at the contents of the SpamFilter\corpus\corpus.ini files which carries those counts. Can you please provide us with those numbers?

With those numbers yes, we would have expected to have seen at least a few emails stopped by the Bayesian filter. Can you please zip and email us at support@logsat.com a copy of your SpamFilter\corpus directory?
