Plesk: Activate DKIM

Foreword

DomainKeys Identified Mail (DKIM) is an identification protocol for ensuring the authenticity of e-mail senders.

Requirements

Server with Plesk Control Panel
Access to the DNS zone of the domain

Enable DKIM in Plesk

First log in to the Plesk Control Panel of your server and then navigate to the email settings under Websites & Domains → domain.de → Email → Email Settings.

Then make sure that the "Use DKIM spam protection system to sign outgoing email messages" checkbox is activated.

If the option "Use DKIM spam protection system to sign outgoing e-mail messages " is not activated, you can check the box and save the settings using the Save button.

Store DKIM key in DNS

After activating the option, the DKIM key can then be called up under "Configuration of the external DNS ". Here you will find all the information on how to create the necessary DNS entry.

Example DNS entry

Please note that the DKIM key in your Plesk Control Panel differs from the DKIM key mentioned in this example. Please use the DKIM key displayed in your Plesk Control Panel.

You can find instructions on how to create the DNS entry if your DNS zone is managed by creoline in our help center under DNS entries. If your DNS zone is managed externally, the DNS entries must be stored with your provider. Please refer to your provider's documentation.
