As it lists mailboxes, not domains, it doesn't scale to a DNSBL.  A better implementation may be as a sendmail text map file, called from custom header rulesets than to have it looked up under MD.  However, that would require a cron-job to check and update it on a regular basis (includign any needed reformatting), while MD could work with it from a remote host UDP or TCP connection.
