I don't see how unknown_hostname_reject_code or
reject_unknown_helo_hostname will help us here.

Yes, am aware unknown_local_recipient_reject_code, and that would be
what we wanted if we were running Postfix on the mail-storage server.
But we deliver mail directly from the mail front-end to the Dovecot LMTP
agent on the mail store.

I forgot to mention that we use Dovecot 2.0.9.
