I've deployed a Symantec Brightmail solution, and after talking to the sales engineers there, I learned interesting info on the Barracuda.
Apparently, this is more or less a white box pc with spamassasin, some custom rules, and bayesian filtering. The effectiveness of this isnt quite as good as some of the more commercial ones (ie Ironport and Brightmail). This also talks to the DNS Black lists, so the effectiveness can be brought into question when the blacklists are blocking legimiate people as well. Brightmail uses a reputation based system, which monitors all the emails it has received across all installations. I've sent somewhere near 60,000 emails with only 1 false positive (this mailing list actually). :) As a plus, I can integrate with OpenLDAP on Imail 8.15 and use it for disregarding email for unknown users.

We currently have around 6000 email accounts using it and it stops allot of junk from getting thru and stops the extra traffic on the actual IMail box. If you want a cheaper solution, you could check out Len's IMGate. I do not have his link handy, but it entails a small box running some *nix functions. Search the archives and you will find all kinds of info on it.

He's offered to let us use it as well for our mail server. Has anyone ever used this appliance? Any opinions on this? Thanks for your time. You can email me off list if you wish. Troy D.
