Hey all-
I'm considering adding some more advanced de-spamming to my email
services. 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?
