[Dovecot] Is there any way to mask or hide the INBOX label for Dovecot 1.2.x Shared Mailboxes?

Hello,

I'm setting up a new Dovecot sever to replace an old Cyrus server, and need to keep things as consistent as possible. I have a couple local accounts, like junkmail and notjunkmail that users get shared access to, and can drop things in to train sa-update. However, when users share over junkmail's inbox, it's displayed in the hierarchy:

• Other Users
	• junkmail
		• INBOX

Is there any way to get junkmail's INBOX to just show up at Other Users/junkmail and not require that extra depth?

• Other Users
	• junkmail

I'm running Debian Squeeze and the standard dovecot package available therein:

# uname -a Linux internet.digitalquay.com.au 2.6.32-5-xen-amd64 #1 SMP Sun Sep 23 13:49:30 UTC 2012 x86_64 GNU/Linux #dovecot --version 1.2.15

I'm running in a configuration where all mail is owned by the vmail user, due to the impression I'm under, that it's a better way if there is to be shared mailboxes.

Relevant bits of dovecot -n:

mail_uid: vmail mail_gid: vmail mail_location: maildir:/var/spool/dovecot/user/%u mail_plugins: acl imap_acl namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: Other Users/%%u/ location: maildir:/var/spool/dovecot/user/%%u:INDEX="/var/spool/dovecot/user/%u/Other\ Users/%%u" list: children auth default: passdb: driver: ldap args: /etc/dovecot/dovecot-ldap.conf userdb: driver: passwd args: uid=vmail gid=vmail blocking=yes mail=maildir:/var/spool/dovecot/user/%u

Am I barking up the wrong tree, or is this possible?

Thanks,

Jay
