In order to avoid spammers hitting the Exchange Server, I would like to stop the Exchange Server sending out non delviery reports where a user is not recongised. Coudl someone point me to how I can turn this off please? I want to simply drop the message
For reference, the non delivery report for users not reconiged is:-
"This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
