I am using Maildir with dovecot 0.99.14-1 and postfix.

My IMAP server was working where I could create a folder in Kmail or Thunderbird and specify wether the folder was to hold messages or folders.
Then something changed, and I lost all my folders that contained sub-folders.
And now I cannot create folders that contain subfolders (Kmail doesn't event give the option anymore). I can create folders and put messages in them, but I cannot create subfolders in the newly created folders.

The Maildir is owned by the user logging in. Do I need to do anything with permissions, or are there settings to allow/disallow this? I've been reading through everything I could find with dovecot and folders in the message, and I can't come up with anything.

Here's an example file structure (logging in as "zta-tech_zach"):
