When creating a white-list, it becomes important to identify the source of the message. Since email uses store and forwarding, originating sources of messages can be difficult to determine, based upon the message alone. Of course DKIM helps with that, but it would be more ideal to shift a greater portion of the burden toward the sender for email to continue to scale. By exchanging only references to messages that are held on-line, the message itself does not need to be initially exchanged. When contacted by a specific source that has been white-listed, your MUA could fetch the desired message from the on-line server at the same time references have been retrieved. When a reference has been falsified, no message can be fetched. This would not demand cryptographic efforts by the sender, or expect receipt of an exponentially increasing volume of junk, or tens or hundreds of DNS transactions per domain to resolve server authorizations. One wonders whether IMAP might be tweaked to provide an online function rather than using traditional URIs. The problem should not be viewed as the 80-20 rule where 80% of the problems are caused by 20% of the sources. This should be viewed as the 99-99 rule, in today's email environment. -Doug
