Fortimanager 400B on 5.0.11 - Enable Alert emails for firewall changes

Hi,

Before we moved to the Fortimanager we had the feature enabled per vdom to email change management if a change was made to the configuration.

Since moving to the Fortimanager i cant see how to enable this option globally so all changes are emailed.

The only thing i can find on the manager that is similar is "event management".  The problem is the changes don't appear in the event logs so they don't trigger an email.
