[otrs] Changing OTRS System notification address

Hello! I have recently inherited OTRS from the previous owner and am having a problem removing his email address. The user, smithj, has been invalidated through the Admin->Users function. Whenever a new ticket is created I am still getting these notifications in the System Log ³Sent email to Œxxx@xxx.com² from ŒOTRS System ¹. HistoryType=>EmailAgent, Subject=> ........² And Sent agent ŒNew Ticket¹ notification to Œsmithj@xxx.com¹ Does anyone have an idea where I can change smithj¹s email to my own? Many thanks! Julian
