Monthly rotation is what Wes was worried about.

Mailbox means subfolder, at least inside Cyrus.

The mboxlist_* and mailbox_* subroutines all only manipulate single 
subfolders. Things like recursive renames happen at a higher level.

I tend to agree. The obvious implementation would be a mapping from 
mailbox name to (really) Unique identifier in the mboxlist. Then a mailbox 
rename would only involve an update to the mboxlist.

However:

1) This would be a very major change.

2) Compatibility with existing mailstores would be a problem.

3) The mboxlist can be reconstructed from the layout on the
    filesystem + the cyrus.header files.
