A major reoragization of buzilla is soon to come.(possibly next week)
The major thrust is to correct QA contacts, and assigees, that are incorrect or no longer active.
As a result, if you are on the cc list for one of the affected bugs, you will receive bugmail.
This might be the time to "clean house" on your cc lists.
Here are some relevent links:
