Use a web interface that requires auth. But I'd not use a milter/policy service--too complicated and unnecessary. Just use a regular access(5) table in db format. Simply write your script to append new addresses or domains to the table with a REJECT action. Then add to main.cf an appropriate restriction such as check_sender_access. Changes are picked up automatically each time a new smtpd is fired so no postmap command is required to make the change active. -- Stan
