What is this crap good for when it sends one out of 1000? There was not a single spam mail that left our system. It was an unwanted mail, not spam but just a message they did not like. We have hard rate limits and a no mass mail policy. We also check ridiculously detailed for patterns of spam.
It's just one of the most stupid systems on this planet that is NOT working because you MS guys are so clever, no, it's still working because of its size. No matter who is responsible. That's sad.
