Excellent news! I read that those messages *can* mean I was blocked by policy, but I'm glad to find out they can also mean the user doesn't exist which is much more likely. I checked my IP for blacklists recently. postfix would not log a 250 if I were blocked, correct? If not, I suppose the log is a good way to figure out if it's a block. - Grant
