If all mail entering the server via SMTP leaves the server via SMTP
(no local deliveries, virtual mailbox deliveries, ...) such a policy

If my response solves your problem, the best way to thank me is to not
send an "it worked, thanks" follow-up. If you must respond, please put
"It worked, thanks" in the "Subject" so I can delete these quickly.
