[MlMt] Suppressing notifications

[Comic Sans]

It seems I found a kind of a solution. I requires defining two smart 
folders, one containing messages you don't want to be notified about, 
and another containing everything else. This seems to be possible 
through adding a condition that Thread-Id is not in the first smart 
folder.

Then I can configure a counter for this folder and voila :)

Would love to know about alternative approaches if any.

Cheers
