Undeliverable Email Message Being Forwarded to Email Address

Somehow the person working before me had set up exchange 2007 to forward all “Undeliverable Email” to his account. Since he is not working here anymore, I need to stop having it forward to him but I am not that familiar with microsoft exchange. If anyone has any idea how to change this, please let me know!

There is a transport rule under organization config called “Undeliverable” but I don’t know if it has anything to do with what I am talking about. It says…
“Apply rule to messages
sent to support
and when the subject field contains Undeliverable: Action Required
apply ExPartnerMail
