Setup DKIM

DKIM stands for DomainKeys Identified Mail and, in short, significantly reduces the chance that mail you send will be marked as spam.

The receiving mail server checks the received email message for authenticity using a digital signature. The server that sends your email (generally our mail server) sends a private key along with your email that the receiving mail server checks based on, among other things, a DNS record that you must set up under your domain.

In this guide, we will explain how to enable DKIM in the Plesk control panel for your email account and how to add the appropriate DNS records to your domain through the DNS settings in My Cloud86.

  1. In My Cloud86 (link), click in the left menu on My Services.
  2. Click the 3 dots behind the web hosting package you want to see in Plesk and click View Details.
  3. Under the heading Manage Webhosting (middle of the page), click on Websites & Domains.
  4. You will now be automatically logged into the Plesk Control Panel.

And that's it! It can take up to 4 hours before all DNS servers are updated and your new DNS records are known. After this time, all your e-mail will be digitally signed with a DKIM key and the chances of your email ending up in the recipient's spam folder will be much lower.
