In the very last version of Thunderbird (currently in beta) the account list appears to be empty, so it is impossible to exclude accounts you don't want to be notified of.
5 stars for all the rest.

This review is for a previous version of the add-on (0.4.3).  This user has a previous review of this add-on.
