reject_unlisted_recipient

Hello all,
Many thanks for all your efforts and a great peace of software. I am
trying to get reject_unlisted_recipient to function. I've put it in
smtpd_recipient_restrictions but with my current setup, the initial smtpd
instance that listens on port 25 just send it right to the content filter
without first checking virtual_alias_maps or virtual_mailbox_maps. See
postconf -n output and master.cf config below. Any assistance greatly
appreciated!
