ColdSpark Announces Support for Cisco Systems and Yahoo DKIM Email Authentication Protocol for the SparkEngine Mail Transport Router (MTR)(TM).

BOULDER, Colo. -- ColdSpark Offers World's Most Powerful Implementation of Key-Signing Email Authentication Protocols

ColdSpark, the leading provider of high-performance email infrastructure and network systems to enterprises and service providers, today announced support for the DKIM authentication protocol in the upcoming release of its industry-leading SparkEngine Mail Transport Router (MTR)(TM). The patent-pending SparkEngine MTR is the next-generation upgrade to today's email network systems and the most powerful email transport application available.

"The DKIM authentication protocol is a promising evolution in verifying the origins of email messages, a critical component in solving the problems of spam, spoofing and other mail security threats," explains Scott brown, CTO of ColdSpark. "ColdSpark champions efforts to improve the quality and security of legitimate email, and helps the world's most demanding companies implement these solutions via the high-performance, flexible SparkEngine platform."

The DKIM protocol uses a unique signature "key" applied to each message by the network of origin that can be verified by receiving networks to prove that a message originated in the location that its envelope information claims. The DKIM protocol is a joint solution based on elements of two advanced encrypted-key protocols: DomainKeys, developed by Yahoo and Identified Internet Mail, authored by Cisco Systems.

ColdSpark is a contributing member of the Email Signing Technology Group (ESTG) of industry leaders who support the development of encrypted-key-based protocols. ColdSpark was one of the first to promote the integration of IIM and DomainKeys, as part of its contribution to the FTC Authentication Summit in 2004 (http://www.ftc.gov/os/comments/emailauthentication/512447-0034.pdf).

ColdSpark's SparkEngine is the world's most powerful platform for encrypted key signing and authentication. With its proprietary connection management for message communications, powerful internal DNS resolver and intelligent disk persistence, the SparkEngine readily supports authenticated email traffic at a sustained rate of millions of messages per hour.
