SAPConnect/Internet mail Gateway issue

Hello,

We have SAP R/3 Enterprise on Windows+Oracle.

We have a probelm of Non Delivery Reports not getting sent to the inbox of the user.

The user says -

____________________________________________________________________

We implemented a SAP application that send emails via Internet.

The batch user that runs the application is BATCH-EDI and its associated mailbox is edi.csg.sap-at-xyz.com

We would like to receive the Non Delivery Reports in this mailbox in case the recipient does not exist any more. But no Non Delivery Reports is sent back in this case to the mailbox.

______________________________________________________________________

I believe from SAP R/3 Enterprise, we do not have Internet Mail gateway.

We have SAPconnect instead.

Could you please tell me how I can configure Non-Delivery Reports to be sent to the mail address.

Thanks.
