      ... Look at the output from postconf -n , then become familiar with Postfix documentation. man 5 postconf , in particular. It should be pretty obvious.

        Look at the output from "postconf -n", then become familiar with
        Postfix documentation.

        "man 5 postconf", in particular. It should be pretty obvious.
