you can merge all smtpd_*_restrictions in smtpd_recipient_restrictions.
Use reject_unauth_destination and reject_unlisted_recipient to reject unknown 
recipients:

smtpd_recipient_restrictions =
        permit_mynetworks,
        reject_unauth_destination
        reject_unlisted_recipient
        check_helo_access hash:/etc/postfix/helo_access,
        reject_invalid_hostname,
        reject_maps_rbl,
        reject_unknown_sender_domain,
        reject_unknown_recipient_domain,
        reject_non_fqdn_sender,
        reject_non_fqdn_recipient,
        reject_unauth_pipelining,
        check_relay_domains
	permit
