Whoa!!! I think the reenable is needed by Kowalski, and not everyone on the
list.
I would assume bounces would be some sort of automatically generated reply
to messages from the list, or mail messages from the list which did not get
through to a particular recipient. When leaving for vacation it is wise to
not have automatically generated out of office replies to lists. Such
replies should be reserved for customers or friends who need to know you are
away.
