Hi Chris,
Joseph, I'm running sa-stats which only pulls out the numbers, what do you use to parse out the info you posted?
On my test box I'm running MailScanner + SpamAssassin and a utility for MailScanner called MailWatch. Essentially this throws all the data from each message into a MySQL database and provides a php frontend.
I've just made up a few php scripts to create summaries by pulling relevant log details from the MySQL db.
Looking at the SURBL stats, the messages that are in the end marked HAM are borderline. Some of them are postmaster bounces or postmaster messages from other servers I maintain, others are questionable mailing lists or even spam sent via yahoo groups.
From my look into the "false positives" of the SURBL lists there's
hardly a message that wouldn't be missed if it hit the bit bucket.
Regards,
Joseph
