With a thundermail-client I can create a subfolder without any erro and I can use it r (but only first level).
My conf: # /etc/dovecot/dovecot.conf ... mail_location: mbox:~/mail
Under the normal mbox storage layout, you cannot have mailboxes (folders) which contain both messages and child mailboxes (subfolders). The reason is explained in detail at the beginning of http://wiki2.dovecot.org/MboxChildFolders .
So with your present set-up you won't be able to create a folder under INBOX.
You can create folders at the top level, but you won't then be able to make subfolders in those.
To be able to nest folders freely, you could:
Switch your mail storage to one of the other formats: Maildir (Dovecot 1.0 onwards), single-dbox (Dovecot 1.2 onwards), multi-dbox (Dovecot 2.0 onwards).
Use a specialist scheme (Dovecot 2.0 onwards) to allow free nesting under mbox - see http://wiki2.dovecot.org/MboxChildFolders
Also worth noting that the current stable version of Dovecot is 2.0.x.
To be able to get best help on the mailing list, I would say try to use at least version 1.2.x of Dovecot.
