Yahoo! Aims to Stop Email Spoofing

LOS ANGELES -- Internet services company Yahoo! said Friday it is developing technology using a new way to authenticate senders in an effort to stop junk email from phony senders.

The technology, called "Domain Keys," would embed a code, called a key, in a message header. The recipient mail server would check the sender's Domain Name Server to see if it had a public key to decode the private key. If it does, the system would consider the sender authentic and pass the message through. If not, the system would block the message as junk email.

Yahoo! said it hopes to have the technology ready by 2004 and would make it available free to open-source email software developers and systems.

"One of the core problems with spam is we don't know, Yahoo doesn't know, the user doesn't know ... if it really came from the party who it says it came from," Brad Garlinghouse, vice president for communication products at Yahoo, told Reuters. "What we're proposing here is to re-engineer the way the Internet works with regard to the authentication of email."

The system could be effective even if only a handful of major ISPs adopt the technology, he said.
