In this task, users can optionally manage their own Email settings.
Link:
Screen Help - User Email Settings
NOTE: This screen is for users who manage their own Email setup, such as their user name and password. These settings are identical to those on the Email tab in the User Setup screen, where Email setup is managed by the system administrator. If a user does not personally manage his or her Email setup, we suggest that you use password security to deny that user access to this screen.
