Good comments on the infoworld anti-spam tests. I know your pain with respect to managing evaluations.  

You probably missed my marvelous prose due to your recent purge but the Infoworld results are even worse than meaningless. They are wrong. The calculations didn't include messages dropped by reputation filtering as spam. So anyone who does this has their capture rate totally skewed. 

But more importantly spam tests continue to test the wrong thing. Capture rates are meaningless because as you say everyone get the same basic amount of spam. The critical measures are resilience and response time to new outbreaks.
