Well, the issue is, with mbox, you can decide if the name you create:

a) can hold child mailboxes, or messages


b) messages, and no mailboxes

it makes more sense when you think about them as directories and files. WIth mbox a mailbox is a file. So:


in such setup inbox is a file and of course you can't create ~/mailbox/inbox/children files or directories. but ~/mailbox/foo/ is a directory, so you can create files or directories under it. But the foo itself is a directory, not an mbox file.

So with mbox the important thing is to either add nor not add the '/' trailing character to created mailbox names.

(And to think that with BikINI they thought this was a good feature of IMAP, not a bad one..)
