Thanks, after an off-list reply suggesting just that I tried that out,
and that works like a charm. Adding the client to mynetworks won't cut
it, as I don't trust the system except for the fact that I can control
the traffic between the system and the smarthost; authentication is a
must so that I can trace whether the host does "bad" things.
You can trace that regardless, since postfix logs what happens.
However, only SMTP AUTH combined with smtpd_sender_login_maps and its
various restrictions allow you to /control/ what happens.
