How are you trying to create the folders?
With mbox you have to create the folders with a trailing slash "foldername/".
You can only have either a folder or another mbox, but you can't have both.

I never thought usermin as a webmail client was very good anyway. It seemed as 
more of a kludge then polished software, especially when accessing mail by IMAP.

I still have problems with outlook on pop3, especially if the mail is left on 
the server and also accessed with another MUA like outlook express -- don't 
ask -- stupid PHB decision -- but I haven't had other problems. I have 
Thunderbird as my MUA of choice, but also have both outlook and outlook 
express accessing my IMAP store occasionally for testing and debugging 
purposes. I'm also testing several webmail softwares on the same mail store 
and I haven't seen any gotchas.
