You mean that after I put "unknown_address_reject_code = 550" on main.cfthe ones rejected with 550 are due to my rule and the ones rejected with 450 are due to lookup errors? If yes, it's VERY strange, DNS is responding for sure now. No doubt about it. And, second thing: if a domain is not existing you consider this a lookup error? DNS responds and tells postfix that domain doesn't exist. Shortly: for me it's ok that postfix replies with 450 for lookup error, but is there a way to force him to reply with 550 if DNS is responding and domain is not existing? Thanks, Andrea
