then use some whitelist ...,should be enough i.e

smtpd_client_restrictions = permit_sasl_authenticated,
                            permit_mynetworks,
                            check_client_access
hash:/etc/postfix/white_client_access,
                            reject_unknown_reverse_client_hostname,
