Understanding DKIM

DKIM stands for "DomainKeys Identified Mail." DKIM can be thought of as a sort of digital signature on all your mail. When you send out mail with DKIM enabled, it has your unique signature attached to it and the recipient can be certain where it came from. Consequently, if someone else sends mail under your name when you have DKIM enabled, the recipient (or their spam filter) will see that the mail doesn't have your signature and therefor is not authentic mail. This can occasionally have adverse affects when forwarding emails repeatedly, which can cause the recipients to receive email from a potential unsafe sender who does not carry your same DKIM signature, causing it to be incorrectly marked inauthentic, though this is very rare. You may find more in depth information on the DKIM standard here.

Configuring DKIM

1. First, you will want to navigate to the Fused client area here and log in
2. Once you are logged in, click the "Services" text on the blue bar at the top of the screen (just below the Fused branding). From the drop down menu that appears, click on "My Services"
3. On this page, you should see your services listed by domain. For any active domain for which you want to configure the DKIM record, you may click on the green "Active" button to the far right of the domain to advance
4. You will then be taken to a page displaying the details of the service for this domain. On the left should be a table labeled "Actions" containing a list where you will click the "Login to cPanel" option
5. Once logged in, you will see a search option at the top right of the screen. If you type in "DKIM" and press enter, you will be taken to an authentication page detailing your current DKIM record and giving the option to "Enable" or "Disable" the DKIM functionality of this domain, along with additional SPF configuration options and records
