I'm looking to set up a spam filtering server to replace our ISP's spam filtering service.
I've seen this tutorial ( ftp://orn.mpg.de/pub/unix/mail/Fairly-Secure_Anti-SPAM_Gateway_Using_SpamAssassin.html#antivirus ) and I'd be very interested in YOUR opinion; do you think, fundamentally, a server with these software packages could be an effective combination at fighting spam? We're a (I guess) medium size organization with appx. 1000 end users. What about weaving clam-av into the mix? Although this tutorial uses OpenBSD, I'll probably be using FreeBSD. Thank you for your input! :-) Ed
