--- Comment #1 from Heiko Schlittermann <[email protected]> ---
We should log when a delivery to a remote host was temp rejected. Currently we
don't do. The failed attemps are just visible from some indications (TLS
traces) and such.

The following log except should(!) show that we had a 4xx when talking to
mx00.hj-systems.de

The 14:47:24 entries are a multi-line log, but they do show the 4xx error
  451-Rejected due to site policy reasons
reported by mx01.hj-systems.de

I see similar log entries on my home server
(although I only appear to have received 5xx errors).
