Need opinions please…

Recently I’ve come across a program from Sunbelt Software called Counterspy which is an antisyware program available for personal and enterprise use. The company has also very recently come out with a product called Sunbelt Messaging Ninja which is an anti-virus, anti-spam solution for Exchange 2000/03. Please take a look www.sunbelt-software.com.

THIS IS NOT AN ADVERTISEMENT FOR SUNBELT SOFTWARE! I am merely trying to get the opinions or experiences of veteran, in-house netork/system admins of this new solution.

Given this info about Sunbelt, how would you stack their Messaging Ninja aginst say, GFi’s MailEssentials and MialSecurity?

I thank you all in advance for your opinions.
