Hard to imagine how you reached that interpretation. Postfix rejects invalid relay recipients for domains list (only) in relay_domains, when there are no wildcard matches in that table or matches in canonical_maps or virtual_alias_maps and when invalid recipient validation is not disabled. The simplest test is to configure an empty relay_recipient_maps, and see whether any relay recipients are allowed then. Try (on a test server): relay_domains = whitehouse.gov relay_recipient_maps = inline:{@=@} When I do this, and run a test, I see: rcpt to:<presid...@whitehouse.gov> 550 5.1.1 <presid...@whitehouse.gov>: Recipient address rejected: User unknown in relay recipient table quit 221 2.0.0 Bye Do you? -- Viktor.
