"Empty" means empty in the sense of "contains zero bytes" rather than "contains zero messages" (since it describes a file rather than a mail folder). I was thinking that the passage neglected to specify what happens if the mail folder file INBOX does not exist, but then I realized that I was making another subtle misinterpretation. I think I grasp now that INBOX is the imap abstraction equivalent to the mail folder INBOX in $HOME or, when this does not exist, the incoming mail spool file. But still, even with this understanding, what happens if there is no INBOX at all?
