Sender Policy Framework

New anti-spoofing protocol built on SPF

Fifteen leading email service and technology providers are today announcing DMARC.org, a technical working group that has been developing standards for reducing the threat of deceptive emails, such as spam and phishing. DMARC.org draws upon a history of private industry collaboration with 18 months of dedicated work, to outline an enhanced vision for email authentication that can scale up to today's Internet needs. The group's work includes a draft specification that helps create a feedback loop between legitimate email senders and receivers to make impersonation more difficult for phishers trying to send fraudulent email.
