Tracking Error in senting mail through SO_DOCUMENT_SEND_API1

Hi Gurus,

I am using the FM SO_DOCUMENT_SEND_API1 to sent mails via custom programs. In many cases, when email id's does not exist or mailbox full for the receipient ID, it is throwing error in SCOT. Is there any option through which I can track those mail id's which are failed from sending successfully in my program. Please advice.

Regards,

Harish Haridas.
