Aug 3, 2009 We have done some additional testing and have eliminated the primary issues with the additional spam filtering servers, and we are now offering this service to domain customers at no additional charge as an optional service. Please see ourknowledge base for more information.
July 29 2009 – We have removed the additional spam filtering from our servers. It will take a couple of hours to propagate the change, but you should see mail (and the level of spam) go back to the way it was last week. Please pass our apologies to your users.
The tests we ran on the system were very successful, and the spam filtering capabilities were excellent, however, as a whole, the few problems we experienced were not worth the value. We will reevaluate, do additional testing and move forward in the future.
