On Thursday, Google added DKIM signing to their Google Apps offering . This is great news for everyone as it strengthens mail receiver’s abilities to block mail forgeries and provide reliable domain reputation.
Both Google and Sendmail have had a long history with DKIM. Sendmail helped draft the first DKIM standards as well as launched one of the first open source DKIM implementations. Google has also been verifying eBay and PayPal incoming messages since 2008 and now says, “Google Apps is the first major email platform – including on-premises providers – to offer simple DKIM signing at no extra cost.”
While I welcome Google to the party, I have to disagree with that statement. Sendmail has included both full DKIM signature verification from all domains as well as full DKIM signing on all outbound mail in our on-premises messaging platform, the Sentrion MPE, since 2008, at no extra cost. For those who use Google Apps in a hybrid mail architecture, the Sentrion MP integrates with Google Apps to take advantage of on-premises protection for their outbound mail against compliance violations, policy, use encryption, and even DKIM signing.

I look forward to more cloud e-mail providers following Google’s lead by providing full inbound DKIM verification and outbound DKIM signing.
