I'd like to provide content filtering (for virus signitures, buffer overruns in subject lines, etc, etc.) Also, ideally, real time blocking for inbound spam. IE: I've recieved 20 copies of the same message for different customers, I'm going to spool all further messages that look like this one for manual processing (approval or rejection by the postmaster) in a a single group. Currently I am more concerned about inbound SMTP than what my customers are sending. So- what I'm asking is: what mail server could be used like this (after a message passed the filters it would be forwarded to the existing pop3/smtp server.) I've heard that you can do this with Sendmail (although its way above my head) but I've also heard that procmail and qmail are the best choices. Anybody have any experience doing this? What qould you recommend? ----------------------------------------------------------------- Kelsey Cummings System Administrator NetEase, Inc. kc@neteze.com ----------------------------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
