Remember, the navigator used to poll all of the folders for
new mail every time you refreshed it, and come up with a little
message box.

That's great, right until you start accumulating mail, and the
IMAP server suddenly gets bombarded by the need to open up
hundreds of folders for every navigator request (many of which
never get mail delivered to them regularly, and so would never
have new mail).

So, the idea of polling is that you match up which folders could
receive mail, and only poll those, leaving your archive folders
to be cached.
