The following is an announcement I posted to a number of email authentication discussion lists earlier today. Its an important release by our company and an important step for the evolution of email. Its also one of the things I’ve been working my butt off on lately. =)

As part of our broad-reaching effort to spur the testing and eventual broad adoption of sender-based email authentication to address fraud and spam in email, Sendmail, Inc. is releasing an open source implementation of the Yahoo! DomainKeys specification for testing on the Internet.

This implementation, part of the Sendmail Messaging Integrity program, utilizes the milter interface to plug directly into the sendmail MTA. To speed the adoption of sender-based messaging authentication schemes, Sendmail is aggressively testing these implementations in the Pilot Program. The goals of this program are to:

* Deploy and test milter-based implementations of sender authentication schemes like DomainKeys and the evolving merger of Caller ID for Email and SPF.
* Encourage diverse user communities to thoroughly test different sender authentication approaches using real-world use cases.
* Develop additional testing scenarios based on feedback from program participants and like implementations of sender-based messaging authentication.
* Share and publish results in a community forum purpose-built to share ideas about email authentication.

Sendmail is actively seeking participants and feedback for this Pilot Program. For more information about how you or your organization can get involved in piloting the next generation in fraud and spam protection software, please visit:
