Okay, I see now that use of the postconf -x myyadayada reveals the actual changes. Perhaps I am not understanding this properly. My server hostname is say mail.internal so right now any mail going out ends up with the from field populated as
user@mail.internal which will not fly with most relays. So I want to use mydomain = valid.com then set the following myhostname=$mydomain myorigin=$mydomain The postconf -x myhostname now reveals the proper 'myhostname = valid.com', which is great. But, outgoing mail is still reading from field as 'user@mail.internal'. Is this correct behavior that I am just misinterpreting as a problem?

Viewing the system journal created, I can see test emails using the default system settings for hostname and domainname instead of those specified in the main.cf file. I will try the -o parameter next to see if I can force the values.
