Dear Morten!
Let me disturb you again.
I don't receive alert massages at all. Alertengine works, I'm admin with all permissions, Filter group "all filters", email is correct. 
We've disabled cables, but nothing received
what could it be?

Disabling the ports won't take them away. This is blown-up view is,
unfortunately, a side effect of NAV not being able to get module
information from the ports. If it did, they would at least by grouped by
module.

The port reports might suit you better in this case.
