OTA Endorses Domain-Based Message Authentication (DMARC)

Thursday, February 02, 2012



Leading email service and technology providers and organizations including the Online Trust Alliance (OTA) announced the formation of DMARC.org, a working group focused on developing standards for reducing the threat of deceptive emails.

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. 

DMARC standardizes how email receivers perform email authentication using the well-known SPF and DKIM mechanisms.  

"Since 2004, OTA has been on the forefront of advancing best practices to restore trust in email and to protect consumers from harm. We are excited about the promise of DMARC and how it builds on these efforts enhancing brand, business and consumer protection." - Craig Spiezle, Executive Director & President Online Trust Alliance.
