[Dovecot] INBOX un-subscribable (is that a word?)

[Jim Horner]

I am trying to get open-xchange installed and working (which after two days 
might be futile). In doing this I noticed that no email client can subscribe 
to INBOX. I'm using rc10 and my namespaces are the following. 99% of the 
email clients ignore the inability to subscribe to INBOX and display all the 
folders underneath anyway which is why I've never noticed this issue... 
however, open-xchange is not in that camp and only displays messages in 
INBOX. All folders are in the subscriptions file including INBOX but all 
email clients always list INBOX as not subscribed to.

COMPANY are ROOTMAIL are share folders with ACLs in /etc/dovecot/acl and those 
top folders are not subscribable either.


namespace public {
    separator = .
    prefix = COMPANY.
    location = 
maildir:/home/services/mail/arinbe.com/arinbe/Maildir:CONTROL=%h/shared-settings/company/control:INDEX=%h/shared-settings/company/index
    hidden = no
    inbox = no
}

namespace public {
    separator = .
    prefix = ROOTMAIL.
    location = 
maildir:/home/services/mail/arinbe.com/rootmail/Maildir:CONTROL=%h/shared-settings/rootmail/control:INDEX=%h/shared-settings/rootmail/index
    hidden = no
    inbox = no
}

# default namespace
namespace private {
    separator = .
    inbox = yes
    hidden = no
    prefix = INBOX.
}
