Thus a folder called 'holidays' is actually a directory called 'INBOX.holidays' and a folder called 'holidays/france' is a directory called 'INBOX.holidays.france'. Why any sort of mail server would want to construct a folder hierarchy like this I can never understand.

IMAP pretty much requires that you can find all the folder names pretty quickly. Having folders stored like this means you can find all folders with a single directory scan, without having to walk a whole filesystem tree.
