this is unsfae. use
smtpd_recipient_restrictions =
permit_mynetworks
reject_unauth_destination
check_sender_access dbm:/etc/postfix/blocked_senders
reject_rbl_client 67679988282.rbl.com
reject_unauth_destination prevent open relay, and should be used before
check_* when maps could return an OK (accidentally or not). it is also
cheap (compared to an rbl lookup, even if it's a local rbl).
