3223182 - Mandatory DKIM setup - SAP S/4HANA Cloud Public Edition

Sending emails from the system does not work after changing e-mail domain. 

SAP S/4HANA Cloud Public Edition

Setting up Domain Keys Identified Mail (DKIM) is mandatory if it is desired to send emails from the system.

Securing the email using DKIM became mandatory since SAP S/4HANA Cloud Public Edition 2208 release.

The purpose of this task is to apply the email security standard DKIM to emails sent by the SAP S/4HANA system. With that it is possible to 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 the Domain Name Server (DNS) with information provided by SAP.
3. Finally close the request once the setup is in place and validated.

Afterwards, the business email is sent using DKIM.

1. Log on to SAP for Me.
2. Under Dashboards, choose Services & Support.
3. On the Service Requests tab, choose New Service Request. The system displays the New Service Request dialog.
