...Cloudmark Exchange Edition(TM) (CEE), the easy-to-use, server-side, anti-spam solution, specifically for small and medium businesses (SMB). CEE is powered by Cloudmark SpamNet(TM), the most accurate desktop solution as proven by customers and PC Magazine two years in a row, to stop over 97 percent of spam automatically without losing business emails.

By taking advantage of automatic real-time updates from the SpamNet community of more than 900,000 users, CEE delivers instant spam protection with no configuration and no maintenance to meet the needs of SMBs that often operate with little to no IT staff.

My favorite spam fighting company Cloudmark has finally entered the Enterprise arena with their new Exchange integrated server side product.  The new solution called Cloudmark Exchange Edition (CEE) leverages their existing community of users to flag spam. 

My concern, while I haven't seen the architecture but can infer how this would work, is that I don't see to many companies opening up their mail servers to allow real time access to such a feed.  Take anti-virus signature update feeds for instance.  Most companies don't setup a server to just go out and download virus signatures and then automatically distribute them.  Things just aren't done that way.  Most companies have someone assigned to the task of anti-virus signature file testing and distribution. 

I see the same model evolving here.
