Internally you could use a Connection document to an SMTP cluster name from Domino spokes in a different NNN. There is an enhancement request for this functionality. Open a service request with IBM Support to log an additional request for this feature under SPR #SSHE5B8TQR. Best Regards! Rodrigo San Vicente
