Daniel Dreymann the co-founder of Goodmail, the company whose product range includes CertifiedEmail recently wrote on his personal blog that Goodmail are to adopt the use of DKIM as an authentication method rather than relying on a standard which goodmail themselves had designed and implemented involving RSA key pairs and SHA-1.

Daniel said:

“It was a relatively simple matter for us to substitute DKIM for our original authentication layer. The authentication layer was, and still is, a rather prosaic component of CertifiedEmail. The other security components, the “secret sauce” that made CertifiedEmail the best and the only secure email certification system, remain in place. DKIM-based CertifiedEmail is as secure as the original specification of CertifiedEmail.”

The benefit to marketers and IT staff here is that rather than having to run and maintain specialised MTA’s from vendors like Port25, Strongmail, Message systems and Socketlabs nearly all off the shelf mail servers will support DKIM signing on outbound messages. This allows organisations to use CertifiedEmail from Goodmail on your outbound corporate email as well as emails you send through your ESP (Email Service Provider).
