> I'm pretty new to imap... is this correct behaviour? Yes. Under "normal circumstances" (altnamespace off), only the INBOX (and its subfolders) belong to the user, so he cannot create any folders outside it. Trouble is, this differes from the UW IMAP server, which allows personal folders outside the INBOX hierarchy, and many people had got used to that behaviour. Altnamespace placates these people by making subfolders of the INBOX look like seperate top-level folders. Of couse, as a side-effect, INBOX becomes something special which cannot have subfolders. I prefert to train my users in the Cyrus way of thinking and leave the altnamespace off.
