The Anti-Spam SMTP Proxy (ASSP) Server project aims to create an open source platform-independent SMTP Proxy server which implements whitelists, Bayesian, and basic anti-virus filtering to rid the planet of the blight of unsolicited email (UCE).

The issue does NOT affect versions other than 1.3.3
All users of 1.3.3 are urged to update.
