This isn't a huge problem, but it would be nice to get cleaned up if possible.

Occasionally we have discovered empty directories in a user's spool area. Empty means no cyrus.* files, or messages. They are not in the mailbox.db as a current mailbox. I have discovered that if the folder to delete is first selected, all files are removed (including cyrus.*), it is removed from the mailbox db, but the (empty) directory remains on disk.

I've also duplicated this by just telnetting to the imap port, created a folder, selected it, then deleted it. The directory remained.

What I have found is the directory does not remain if the folder is not selected before the delete. Here's a log of the one that leaves a directory:
