That said, the DCC whitelisting approach is really only practical for small sites. I think it would be most appropriate for the SA mass-checks to be based on DCC's performance without any whitelisting. I administer SA for over 100 users, all of whom have different bulk senders. I whitelist some of them, and also handle them on a post-FP basis when reported, but there's no way I can keep track of all of the thousands of legitimate bulk senders at my site. Now picture the problems faced by someone who administers an email system with 10,000+ users. Since SA is really targeted at server-side use, it needs to be focused on some of the practicalities of large-scale deployment.
