Hi Avadhesh,
You mentioned it as Non-Production system right??
So first check whatz the need to send mails from an non-productive system. I guess you might only send it to basis people for system monitoring.
And define those mail'ids which you want to sent the mail's .
I dont think it's possible to filter the mail id's anywhere else. Only option SAP provided is SCOT transaction.
Here * allows all the mail'ids else you need to specify the mail id's which you want to sent the mails.
Thanks and regards,
