That defeats the use of the policy server. The purpose of the policy server is to help determine if it should be queued or rejected. If we queue it, then it's hard to reject it at that point. I guess you could, but you would end up with backscatter from spammers. In the end, postfix is doing what is should. It is saying, hey, I can't accept this message right now, try again later.
