Yahoo is teaming up with eBay and its PayPal unit to block fake e-mails that are targeted towards Yahoo Mail users. Yahoo's own technology called DomainKeys is being used to authenticate the senders of e-mails.
A quote from the article at Reuters:
The technology upgrade will be made available to Yahoo Mail users worldwide over the next several weeks, the company said. "It is a big step forward for consumers in defense against the bad guys," John Kremer, vice president of Yahoo Mail, said in a phone interview.
DomainKeys verifies the DNS domain of an e-mail sender and the message integrity. The technology will be rolled out globally over the next few weeks.
Phishing scams have been a major worry for financial institutions, faking authenticity and making users divulge sensitive information. Cooperation and collaboration among various technology entities are a welcome sign in an age where "standards" are the hardest to standardize.
