I have no problem not GREYLISTING things that pass, that's how the original question was laid?? Of course you can and should use blacklists etc. But why greylist retrying servers? Or maybe someone will point out that snowshoers don't retry? Only thing you might win with greylisting is some 5 minutes for blacklists to catch up. One could speculate that it might not matter much.
