This works like a charm. One last thing, concerning order of smtpd_recipient_restrictions, I currently have this in master.cf : submission inet n - - - - smtpd ... -o smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject_unknown_recipient_domain,check_sender_access,hash:/etc/postfix/verify_recipient,reject Can you confirm that in case of greylisting at the destination SMTP, it will work fine ?
