World's leading email providers including Google, Yahoo, AOL, Facebook and Microsoft have announced to join hands to collectively fight the increasing menace of email and phishing attacks.

Following 18 months of collaborative work, 15 email providers on Monday announced formation of DMARC.org (Domain-based Message Authentication, Reporting and Conformance) a technical working group to develop standards for reducing the threat of deceptive emails, such as spam and phishing.

Among other things, it will 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.

"Email phishing defrauds millions of people and companies every year, resulting in a loss of consumer confidence in email and the Internet as a whole," said Brett McDowell, chair of DMARC.org and Senior Manager of Customer Security Initiatives at PayPal.

"Industry cooperation - combined with technology and consumer education - is crucial to fight phishing," McDowell said.

The DMARC specification addresses concerns that have traditionally hindered widespread deployment of an authenticated, trusted email ecosystem, the statement said.

"Today, email receivers lack a reliable way to know the extent to which an email sender uses standards like SPF and DKIM for authenticating their messages," it said adding that as a result, providers must rely on complex and imperfect measurements to separate legitimate unauthenticated messages sent by the domain owner from fraudulent phishing messages sent by a scammer. .
