For the case, mail server is not necessarily a Postfix. Yes it is a workaround to find different myhostname variable setting then hostname of the real mail server.
internet -> postfix relay -> mail server mail.mydomain.com mail.mydomain.com However, this needs a control: - new myhostname should resolv to the same IP and the IP to the same myhostname for a best practice antispam configuration. - The customer may not have any other hostname defined in the DNS. So, those cases will need a control and will not work seamlessly. I just wanted to ask If Is there a way to disable "loops back to myself" errors in a case which is not actually a real loop back. Thanks Mr. Venema.
