We've just recently gone from NAVG to a different setup. Currently we go Barracuda > NAVG > IMail. The Barracuda does Virus scan, blacklists, and Bayesian filtering, then forwards it to the NAVG machine which is only doing Virus scan, then forwards to the Imail server where it is scanned yet again by the IMail AV software. - Sort of a belt and suspenders and duct tape approach to virus scanning ;-)
We were using NAVG and had a large number of false positives and no truly noticeable difference in spam passing thru to users. I spent up to 2 hours daily sorting thru the tagged spam messages forwarding them thru to users. We are just finishing a 30 day trial of the Barracuda product and I will be putting thru the P.O. for it after I finish this email. The Barracuda has been very easy to administer, it can email each user every day with a link to their spam folder and allows them to forward/delete/blacklist/whitelist each email addressed to them that the system felt was spam. It took a lot of work off my shoulders and I've only seen one false positive out of 250,000 messages in the past month.

OK, I've got a small question, I know what I'd like to do, but I want to know what you all do as mail admins. We run a ASSP > NAVG > imail setup, my suggestion. I plan on getting rid of NAVG for declude anti-virus in the near future so thats not an issue. Currently the former admin is catching all suspected spam, and refusing it, never even makes it to NAVG, while I do partly agree with this, it's an all or nothing approach, with the possibility of losing business due to false positives. ASSP has a setting that lets you copy all suspected spam to an email address, I've done this on other networks and it works fine, if theres a false positive, I go find it, put it in that person's account and life goes on, once a week it gets purged. Does anyone else do anything different? Thanks!
