IMAP directory structure.

[C5ace]

Hello,

I use Dovecot 2.1.7. and like to know how to force the IMAP directory 
structure to be:
The IMAP server's desired directory structure is:
root@server-2:/var/vmail/c5ace.com/test/Maildir#
/.INBOX
/.INBOX.Archives
/.INBOX.Drafts
/.INBOX.Junk
/.INBOX.Sent
/.INBOX.Templates
/.INBOX.Trash

and to prevent the mail clients like Thunderbird, Claws Mail, etc. to 
add additional out of tree directories.
Thanks in advance.
Elmar
