[Dovecot] IMAP Folder Creation

[Zach Hobbs]

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"):
