Mail Server Registries and Foreign Sender Authentication: A Proposal

Greetings,

I was recently discussing various issues surrounding email with a
coworker and had a couple of ideas for authentication systems that I
would like to get some feedback on. You can read my ideas at
http://perlstalker.blogspot.com/2007/03/mail-server-registries-and-foreign.html.

As I said, I'm looking for feedback. Are these ideas worth pursuing or
am I barking up the wrong tree?

Thank you for your time.
