WASHINGTON -- Internet portal Yahoo released an e-mail standard Tuesday that
prevents spammers from hiding unwanted messages behind legitimate e-mail
addresses.

The technique, if widely adopted, could help Internet service providers more
easily block the unwanted bulk messages that currently account for up to
two-thirds of all e-mail traffic.

Yahoo's proposed standard, known as DomainKeys, would embed outgoing
messages with an encrypted digital signature matched to a signature on the
server that sends the message.

Internet service providers could check the signatures on incoming messages
and block those that do not match up.
