Each host forwards mail that is not for itself to the other host.

    Traditional (Sendmail style):

        example.com in mydestination
        $myhostname in mydestination
        /etc/aliases:
                w:      w...@host1.example.com
                d:      w...@host1.example.com
                q:      q...@host2.example.com
                r:      r...@host2.example.com

    Modern Postfix style:

        example.com in virtual_alias_domains
        $myhostname in mydestination or virtual_mailbox_domains
        /etc/postfix/virtual:
                w...@example.com        w...@host1.example.com
                d...@example.com        d...@host1.example.com
                q...@example.com        q...@host2.example.com
                r...@example.com        r...@host2.example.com
