Be careful.. some of your customers may be on the same mailing list - a perfectly valid place to be getting mail from. (Of course, you could request that your customers give you the names of mailing lists they are on, but I doubt that'd be real effective, or efficient). > 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? procmail seems to be the easiest way to go.. however, I've never used procmail (while I use FreeBSD to check my mail quite often, I use a program with builtin filters, and thus have no need for procmail...); you should ask somebody with a little more experience with procmail - those I know who use it think it's awesome! -- Will Andrews GCS/E/S @d- s+:+>+:- a--->+++ C++ UB++++ P+ L- E--- W+++ !N !o ?K w--- ?O M+ V-- PS+ PE++ Y+ PGP+>+++ t++ 5 X++ R+ tv+ b++>++++ DI+++ D+ G++>+++ e->++++ h! r-->+++ y?
