ASSP, being a proxy, could probably never handle this. It would be best handled in a full MTA with a queue. > 2) Logfiles processable through Sawmill.

I believe Sawmill had a filter for ASSP at one point. http://www.sawmill.net/formats/anti_spam_smtpproxy.html (google!) Also the logging in ASSP is fine, what you want is log analysis. > Analyzing the errors folder could be a goldmine of useful information in > terms of which filters are the most effective and which ones aren't.

The CCSpam and a few grep searches would probably give you the info you want. > That sort of thing would be very useful in > fine-tuning ASSP's performance. How does adding/removing a DNSBL or changing the scoring of a test "fine-tune" performance? You're talking about effectiveness. They are not the same. > Fritz Borgstedt wrote: >>> Even if this tool is for windows it has nice features like customize >>> filter settings for different domains. >>> >> I did not see one feature, which ASSP does not have. >> There is one actually, "Customize filter settings for each domain". But i think it's a minor feature personally. Others, i'm sure, will disagree. They even have something like the Griplist. http://www.logsat.com/sfi-spam-filter-how-it-works.asp#SFDB Kevin ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
