Hi Lee, Like yourself, Spam has never really been a big issue on my site..... until recently, that is!!! Over the past 6 months I have had more and more irate users yelling at me to do something about it. I have flippantly suggested that I read every single email and manually filter them before forwarding to the correct recipient, but they didn't see the funny side!!! For a couple of years, I have been using "SurfControl Email Filter for SMTP" which handles all mail traffic before it gets to my E2K farm. I recently discovered that it has an Anti-Spam Agent already installed which simply needs to be unlocked. I am currently testing this, and it does seem to be identifying and isolating a lot of rubbish. There are still bits that get through so other methods have to be examined. I try to maintain a dictionary of typical words and phrases for lookups as well as certain rules which block certain senders etc.... Also in "SCEF" are various options to include RBL lookups (Realtime Blackhole Lists), of which I am looking to subscribe to a couple. I understand that this also stops a lot of Spam. Another method is for the gateway to perform a DNS MX lookup and to deny the inbound messages if no DNS entry exists or if the FQDN of the sending mail server in the HELO string fails to match the DNS query for that domain etc.... I don't really have any other product to compare with, but SurfControl, properly configured and installed with the extra Agents, does appear to be a quality mail content/spam/virus/etc. filter. (in my honest opinion) Hope my contribution is at least partially helpful.

Have been using Symantec Exchange 3.0 with the content filter and it's not doing the best job according to some users.... Any thoughts on the subject are appreciated! Thanks!
