OEM 11g alerts and notifications arrive together

Question

I setup the OEM with the Idea to receive Critical messages (emails when the DB, listener, agents and host are down/up) but it doesn't seem to be working. If I "shutdown abort" the database I wont received any message until I put it up and running, so I receive all the messages together.

Please see image Bellow, that's how I set the alerts, I tested the Email sending and it's working.

• Any Idea what it could be?
