I would totally agree that Messaging Architects M+Guardian technology can do a better job. But based on Messaging Architects #'s, when I had them run me a quote on a system, I could not justify the cost to my superiors. Being an educational facility all monies are watched by the bean counters. So they figured we could live with a 10% or less in spam stoppage for the $100,000.00 + difference between Spam/Virus solutions.
Besides, we are slowly convincing our Clients (all 6,549 of them) to use the the Junk Mail Handling/Address Book lookup feature of GW. Which when used with Barracuda gets us as close to a 100% stoppage rate as possible vs. monies spent.
But I see us eventually having to go to a Messaging Architects type system because of the need to be more aggressive in content filtering for pictures and such. Hopefully Barracuda, or others, will come up with as an effective solution w/out the back breaking cost.
My apologies for the rant type reply. But it is an ever ongoing battle between IT and the Business department for us . One watches out for the Staff and Kids while the other watches the coin purse. Both have valid reasons I guess.
