    Not sure that would help. Like qmail, Postfix eliminates itself
    from the list of MX addresses, by recognizing its own IP address.
    This strategy is very robust, even when one IP address is listed
    under multiple hostnames, except when address translation is in
    the game.

    Workaround for Postfix would be to add the A records for $myhostname
    to the list of $inet_interfaces addresses, except that Postfix
    should not try to bind to those addresses because they aren't local.
    This would be necessary anyway to make mail for user[ip.address] work.

    Sort of a "other_inet_interfaces" configuration parameter.
