I've a Linux machine which is used as a final destination for test
emails. Some local inboxes are created, local delivery via Dovecot to IMAP.
I want this machine to never send out any email whatsoever. Never relay.
Accept inbound messages, deliver locally to IMAP - all that is fine. But
no message should ever leave this box, for no reason, even if it's a
notification for delivery error.
I could block outbound port tcp/25 with iptables, but it seems inelegant.
Would this do the trick?
default_transport = error:no outbound emails, sorry
