Using Google Domain Keys (DKIM)
Posted by Trey T on 03 January 2013 10:07 PM
If you use our DNS service, as well as Google's mail service, you may be interested in utilizing domain authentication, which helps servers identify legitimate mail coming from your domain. It is possible to achieve a Google DKIM setup with our DNS service, and it's pretty simple to do so, as well. All you'll need to do once logged into your Sitelutions account is navigate to the Domain Control Center, create the subdomain "google._domainkey" for the domain in Question (be sure not to include any trailing dot, as we want the subdomain to not be fully qualified), and finally, create a TXT record for that subdomain with the value of the key. For example, the subdomain google._domainkey.example.com's TXT record might contain something like:
v=DKIM1\; k=rsa\; t=y\;
Afterward, you should be all set once DNS propagation has completed. This can take 24-48 hours, but it's usually quicker than that. If you'd like to learn more about Google's recommendation for implementing DKIM, please visit http://www.google.com/support/a/bin/Answer.py?Answer=174124.
