| Many thanks Terence and all who have replied. I think I have discovered
the
| problem (and I feel mildly stupid as a result):
|
| I had not spotted that a contact had been set up within our AD, with an
| email address but no mailbox of it's own. Mail received for that address
was
| automatically redirected to the external address for which we had
unexplained
| SMTP queue. So, although we were not acting as an open relay, we were
| relaying any spam which came in to that specific address, and it was
being
| rejected by the SMTP server we were sending it on to.
|
| Thanks again,
| Paul
