Anti-Spam SMTP Proxy Server
Screenshots
Description
The Anti-Spam SMTP Proxy (ASSP) Server project aims to create an open source platform-independent SMTP Proxy server which implements auto-whitelists, self learning Bayesian, Greylisting, DNSBL, DNSWL, URIBL, SPF, SRS, Backscatter, Virus scanning, attachment blocking, Senderbase and multiple other filter methods. Click 'Browse all files' to download the professional version 2.2.1 build 13020.
Note to V2 users build 12265 and less: don't upgrade the module Thread::Queue to version 3.01 - this will cause ASSP to die -> revert to version 2.11/2.12 of Thread::Queue
GUI->Server Setup->AutoUpdateASSP->"never upgrade these modules" or put 'Thread::Queue' in to the file 'files/noupgrade.txt'
2.2.1 build 12313 and higher fixes this problem
V2 users should check the version of 'Regex::Optimizer' and 'Regex::List' in the 'lib' folder - please upgrade these modules to version
Regex::Optimizer - 1.12
Regex::List - 1.06

Bravo! I would recommend this app.

A good alternative to free SpamAssasin and placed it in front of my SMTP server, now I have double protection against spam!
-
Super! Lots of configure possibilities. Only one thing is missing. A daily report to the users to show them all blocked mails for that day, so they can choose to resend the false positives....
