3223182 - Mandatory DKIM setup - SAP S/4HANA Cloud 2208


Sending emails from your system does not work after SAP S/4HANA Cloud 2208 release.


SAP S/4HANA Cloud 2208


Setting up Domain Keys Identified Mail (DKIM) is mandatory if you want to send emails from your system.

Securing your email using DKIM become mandatory with SAP S/4HANA Cloud 2208 release.

The purpose of this task is to apply the email security standard DKIM to emails sent by your SAP S/4HANA system. With that you can make sure messages aren't altered in transit between the sending and receiving email servers. It uses public-key cryptography to sign emails with a private key as it leaves a sending email server.


To enable DKIM on the sending email server hosted by SAP:

  1. Create a request for DKIM activation to SAP.
  2. Update your Domain Name Server (DNS) with information provided by SAP.
  3. Finally close the request once the setup is in place and validated.

Afterwards, your business email is sent using DKIM.


To request the setup and activation of DKIM for your business emails sent by the SAP S/4HANA system, get in touch with SAP S/4HANA Cloud Operations:

  1. Create a service request for component XX-S4C-OPR-SRV using SAP Support Launchpad.
  2. As description, use Request to setup and activation of DKIM.
  3. Use the following template text in the ticket:

Hello SAP S/4HANA Cloud Operations,
Please set up and activate DKIM to emails sent from my SAP S/4HANA system.
SAP S/4HANA Cloud system: Please provide the SIDs or host names or URLs of your SAP S/4HANA Cloud system from which you plan to use DKIM. For example: <>
I want to enable DKIM for the domain <your domain> and top-level-domain <your top-level-domain>. For example:
<Your Name>

  1. Save the ticket.
  2. After the initial steps are done, SAP S/4HANA Cloud Operations will get back to you and ask you to configure your DNS for the domain shared in the request with the provided public key.
  3. Inform SAP S/4HANA Cloud Operations using the service request when the configuration is done.
  4. SAP S/4HANA Cloud Operations will continue the process and get back to you to validate the setup and activation.
  5. Test the DKIM activation and confirm that it works.
