I suppose we need an additional command like option. After all,
"-f <>" sets the envelope sender, so something like "-whatever
mailer-daemon@domain" should set the authenticated sender. It are
really two different attributes. Like -f, its use should be restricted
to trusted users (unless the appropiate option is set). The actual
authenticated sender for bounces should be configurable and default to
the UID exim runs as.
