[Dovecot] IMAP Folders

[Matt Juszczak]

Hi all,

We're using the mbox format and I tried setting up IMAP on my boss's 
computer tonight.

He likes subfolders, and although they work, he can't seem to remove 
subfolders once he created them, nor create new folders without using 
something other than his mail client (like mkdir from the command line).

Any ideas on this?  Does dovecot just not officially support IMAP and 
subfolders with the mbox format?  Or could it be a permissions issue?
