Twitter says it's using a new e-mail security standard to head off phishing-based attacks. "Earlier this month, we began using a new technology called DMARC that makes it extremely unlikely that most of our users will see any email pretending to be from a Twitter.com address. DMARC is a relatively new security protocol created by a group of organizations to help reduce the potential for email-based abuse," Twitter's Josh Aberant wrote in a blog post. DMARC is supported by the e-mail services of AOL, Google, Microsoft and Yahoo.
