If you just want just a list of domains to follow this: Add "check_recipient_access hash:/path/to/faxdomain_auth" after reject_unauth_destination in smtpd_recipient_restrictions (if you do not have one, run "postconf smtpd_recipient_restrictions") /path/to/faxdomain_auth: fax.example.com permit_sasl_authenticated, reject
