After upgrading from 7.2.1 GA to 8.0.0GA, I follow the Wiki: Outgoing SMTP Authentication to configure the authentication password for my relay host. However, I found that all the changes I made with the "postconf -e" command did not stick after "postfix reload" command. It appears that my changes were rewritten by the postfix reload process according to some pre-defined configuration. I cannot find any other place in the Admin GUI to configure the relay host password. Is this a bug or did I miss something?
