[Dovecot] Shared mailboxes and INBOX

I'm trying to implement a shared mailbox: in other words, we have a generic email address ("security@") which we want a number of users to be able to monitor. The problem I have is that users can see folders under that shared mailbox but can't see the INBOX.

All the users in question have their own INBOX in their private namespace, so does this raise a conflict with monitoring another mailbox's INBOX?

Configuration:

# dovecot -n # 1.2.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.2 log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: public separator: / prefix: shared/ location: maildir:/home/publicfolders:INDEX=~/Maildir/public list: yes namespace: type: shared separator: / prefix: security/ location: maildir:/home/securitymailbox/Maildir:INDEX=~/Maildir/securitymailbox list: yes auth default: passdb: driver: pam userdb: driver: passwd
