When Postfix delivers to an unknown user via Dovecot it gets status=deferred but I want a reject in smtpd instead. How fix?
main.cf: mailbox_transport = dovecot:master.cf:
dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver
-e -f ${sender} -d ${recipient}
Running deliver by hand shows it exiting with status 75.
