Not at all. I suggest that you make one more attempt to understand the three address class attributes (transport, domains, valid recipients), and why Postfix needs this to reject non-existent recipients. Unfortunately I don't have the time to on-the-fly improvise a completely new version of ADDRESS_CLASS_README, so that is the source that you will have to deal with. Wietse
