Dave is correct.  The older imapd will show the calendar mailboxes to 
users in the LIST output.  If you want to hide them, you will have to 
install the new imapd binary. Otherwise, you could change the ACLs on 
the calendar mailboxes so that the user can't write to them, but they 
will still see them.
