Yahoo touts anti-spam framework
The Inquirer notes that Yahoo has released a new email standard that will make it harder for spammers to spoof email addresses. Dubbed DomainKeys, the technology uses digital signatures to match incoming messages to the email servers that are supposedly sending them.
DomainKeys is strictly a server-to-server affair, so the system should be invisible to end users. Yahoo plans to make DomainKeys available royalty-free, and they've even submitted the framework to the Internet Engineering Task Force for publication.
