Alert emails from database 10g

Hi List,

I inherited an Oracle 10g (standard 10.1.0.4) database from my previous DBA.

The task is to change the configuration so the the new emails goes to a new email distribution where the previous DBA is not included.

Here's what I did:

In OEM (database Control) went to Set up and changed the "Notification Methods" "Identify Sender AS" and "Sender's E-mail Address" to the new email list.

Problem:

All the emails that still gets generated from the alerts when certain threshold crosses a limit on objects/database still goes to that email address and the email delivery failure notice comes to the list.

Any idea of where the previous DBA's email address is engraved in terms of all the alerts.

TIA.
