I had a similar problem last year with 1.x ASSP. I had both ASSP and SMTP server (listening on 52525) running on same unix machine. Port 52525 was firewalled and the SMTP server was configured to only accept connections from localhost. Somehow spam was getting around ASSP which I knew because I configured ASSP to add X-Assp headers and these were missing. I finally resolved it by writing a filter for the SMTP server that rejected all mail that was missing and X-Assp header. ------ Max Lyth ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
