Question: Mail Downloading Phantom Messages
Mail's Activity Window often grinds away downloading messages. It can take quite some time to work through 2, or 7, or 19 or however many messages Mail is "downloading." Nothing ever shows up in my inbox from this activity. Can anyone explain this behavior, and is it anything of concern?
