Re: anti-spam software

[David Boyer <David () BVU EDU>]

We use a Fortigate at the border to do virus checking and RBL-based antispam. Before the mail hits our SMTP server, it 
goes through an M+Guardian appliance. We've been using the M+Guardian appliance and its predacessor, GWGuardian for 
about 2.5 years. They both work with any SMTP server. We see very few SPAM actually hit mailboxes, and very few 
false-positives.

I am hoping to pick your brains about commercial anti-spam solutions.

The Math Department has roughly 1000 user accounts and currently uses  
SpamAssassin, as well as many of the spam filtering options in  
postfix such as header and body checks and DNS blacklists. Our users  
mark messages as spam and we feed them to the Bayesian database for  
SpamAssassin. Nonetheless, a lot of spam still gets through. So we  
are looking into commercial anti-spam software. Has anyone else gone  
the route of purchasing a commercial solution? If so, how did it work  
out for you? Has anyone else compiled a review of the different  
choices and how they compare? If so, I would love to see it. If you  
know of any commercial anti-spam providers that offer deep education  
discounts that would be good to know also.

Thanks for any help you can give.
