SAP S/4HANA Cloud

2. Set up business rules for the email settings for application, such as billing document
3. Define Sender Email such as test@sap.com and system returns the error.
      
      domain in sender email address test@sap.com is not allowed 

In configuration Define Email Sender Domain, Sender Domain is defined as *@sap.com including character '@'. So the check logic allows a sender email address like <part1>.<part2>@sap.com (with at least one dot and hence two parts on the left-hand side) but rejects <part1>@sap.com (with no dot and hence only one part on the left-hand side).

•  Remove the character '@' in the configuration of Sender Domains
•  Or make sure at least one dot ('.') is used in the left part of the email address
