Hi,
With the amount of spam I have to throw away each day no reaching
consistant levels of over 90%... I can of course get an even faster
mailserver but I think I would be better of with an extra smtp server
in front of my mailserver which filters the most blatant spam mail
purly based on session info. What passes that server can go on to my
IMail server and have more contect based filtering using Declude,
Sniffer, InvURIBL etc.
What would be a good first step server? I have experience with
(Debian) Linux so a Linux based solution is no problem.
A couple of things pop into my mind:
eWall can live on your mail server and kill off most connections while
being trained by SNF. (for example, block IP connections for an hour
after an SNF hit).
Postfix on a linux box makes a good front-end and can also run SNFMilter
in real-time during SMTP.
