Dave That looks exactly what we're wanting. Basically we point our MX records to this spam filtering company and then they push the (cleaned) mail to us. We need to do it only for certain domains though, not server-wide. I'll have a read of the link you sent, so thanks for this

And then they deliver the mail to you based on some nominated hostname (i.e. not MXs)? If so, DNS TTLs permitting, you'll want to permanently reject (deny) attempts by others to send mail to those domains. In general, something like deny domains = somedomain.example.com hosts = !spamfilteringserver.example.net message = Relaying denied placed appropriately in your RCPT ACL should do the trick.
