Caller ID for E-Mail Spec

There's a page up for information related to Caller ID for E-Mail.
From the page:

Caller ID for e-mail would verify that each e-mail message originates from the Internet domain it claims to come from. Eliminating domain spoofing will help legitimate senders protect their domain names and reputations, and help recipients more effectively identify and filter junk e-mail.

    How about just using AMTP.

    Micropayments, postage, caller ID. What suit dreams up these tardlicous ideas.

    I think the email address you posted here is wrong. There might be an extra "s" in it. 😉

    BTW, there’s an interesting discussion on some of the flaws of caller id for e-mail at I hadn’t realized exactly how much more data was required with XML in DNS vs the cryptic text of spf. I imagine hotmail might be sending out quite a bit of data each day in anti-spam xml. 😛
