You can use http://www.postfix.org/postconf.5.html#check_recipient_mx_access to reject mail addressed to domains with bogus MX records. Something like: # main.cf smtpd_sender_restrictions = check_recipient_mx_access hash:/etc/postfix/bogus_mx ... other existing restrictions ... # bogus_mx 127.0.0.1 REJECT bogus localhost MX record -- Noel Jones
