There is a specific filter for acknowleged and confirmed. These are covered under the set on the Manage -> Manage configuration -> Email Notification. The user's access level needs to be selected on that page to receive a message.

Further, the user needs to allow email notifications under "Email on Status Change" (this defaults to off).

Can you check these settings? There is a server logging feature for emails as well.

Ok thraxisp,

I checked all my settings including "Email on Status Change" user setting.
All is correct now; the email notification for ack and confirmed status works.

Thanks a lot ;-)
