Yahoo Inc. is putting its e-mail authentication method into action. On Monday, the Sunnyvale, Calif., company will begin to support its DomainKeys cryptographic approach for Yahoo Mail, one of the largest Web-based e-mail services in the world. Yahoo"s DomainKeys move will come as part of a series of enhancements to Yahoo Mail. The company will announce that it has increased the storage limit for free e-mail accounts from 100MB to 250MB and has raised the maximum attachment size for premium accounts from 10MB to 20MB.
By supporting DomainKeys on its own service, Yahoo hopes to jump-start broader adoption of its answer to stemming the rise of spam and phishing attacks through e-mail. Online attackers regularly send unsolicited e-mails and lure consumers into clicking malicious links or providing personal information by disguising their e-mail addresses with the domains of major consumer companies. "By implementing and deploying DomainKeys, we"re showing that the cryptographic solution is not only the long-term answer but today"s answer as well," said Miles Libbey, anti-spam product manager for Yahoo Mail.
