-------------------------
"One organization working on sender-authentication mechanism is a
commercial alliance comprising the biggest consumer e-mail providers:
Microsoft, Yahoo, America Online and Earthlink."

"Under the proposal, ISPs and any other organization with their own
domain name system (DNS) would use a private key in their mail servers
to place an encrypted code in the header of each piece of outgoing mail.
When the mail arrived at its destination, the receiving mail server
would get the sender's public key from its DNS server to decrypt the
header, thus verifying the message's origin.

If the message is spam, or even a legitimate marketing message the
receiver doesn't want, then email from that DNS can be blacklisted, or
automatically blocked. "Once you have identity, then you can establish
reputation and trust," Libbey said. "Those are really important concepts
in e-mail."

Yahoo has done some proof-of-concept testing of the idea internally, but
the technology is still at the early stages of development and no
timetable for general release has been set."
