New submission from Fabio Pietrosanti <fp at khamsa.ch>:

# Be aggressive in terms of rejection of unauthorized emails
unverified_sender_reject_code = 550
unverified_recipient_reject_code = 550
unknown_address_reject_code = 550
unknown_local_recipient_reject_code = 550
unknown_client_reject_code = 550
unknown_hostname_reject_code = 550

450 simply keep more stuff in the queue of broken systems in my own experience.
