And I understand the reasons for that. But... can't you see how this turns into a "he said / she said" argument? Microsoft: "Your IP sent us spam, so we're blocking you." Mail Server Admin: "I don't see any spam being sent, I don't see the IP on any other blacklisting, can you prove it?" Microsoft: "Uh... no... we can't detail that information - you just have to trust us." Microsoft: "Oh, and by the way, we're ignoring you now... so brownie points for the whole trust thing!" I guess if you block all incoming traffic on port 25 to your mail servers... you're pretty much going to be guaranteed to stop all of your users from receiving spam.
