DKIM, or Domain Keys for Identified Mail is a method to cryptographically sign email so that your recipients are assured that the email:
- Is from the party it purports to be from (is not spoofed)
- Has not been altered
Enabling DKIM for your domain increases delivery rates and reduces the odds of winding up in your intended recipients' spam folder.
It works by generating a private/public key pair, and then creating a specially formatted TXT record containing a public key (the DomainKey), and then installing the other half of the key pair (the private key) on your outbound email server.
The outbound email server then needs to be configured to sign all of your outbound email with the private key.
It may sound complicated, but the good news is any easyMail account here can enable DKIM and we'll take care of the heavy lifting for you. In fact, it's all one click:
