Re: S/MIME Gateway Profile / Yahoo DomainKeys

I tend to agree. I would love to see DK use an s/mime type infrastructure given that so many email clients and servers do know s/mime to come extent. Developers know it too. Might help to speed adoption.

Many people agree that crypto is part of the long-term picture of email.

S/MIME was originally designed as end-user to end-user infrastructure.

Recently a domain-to-domain version has been announced:

 http://www.opengroup.org/messaging/sm/smgdev/doc.tpl?CALLER=index.tpl&gdid=4657

But it still looks heavyweight compared to Yahoo DomainKeys.

Wouldn't it be great if S/MIME could, instead of requiring a
cumbersome and O(n^2) initial key exchange between domains, make use
of opportunistic "oh, look, and here's the cert in DNS"?

Oh, and instead of "cert" read "self-signed public key".

Then maybe we'd get the benefits of the Yahoo DK infrastructure but
leverage the existing S/MIME base.
