Additional notes regarding Outgoing E-Mails:

Outgoing E-Mail Scenarios:

If you choose to use the SAP standard sender address DoNotReply@<system domain> a key pair (needed for decryption and signature) is automatically created and signed by the SAP Passport CA.

If you want to use a different sender address in your own domain, it is required to create a key pair outside the BYD system and upload using the first method shown above. To verify e-mail signatures sent from this address the e-mail recipients must install the corresponding CA certificate in their e-mail clients. For the SAP Passport CA, the certificate can be obtained via the Help center link below. For external key pairs the certificate can be obtained from the signing CA.
