[Dovecot] Imap Ghost folder

[Sascha Zucca]

Hi list,
i have a strange "ghost" folder in my subscription list and just can't 
find out how to get rid of it.
It seems to be someones Inbox, but it doesn't tell me whose.

Here's a screenshot of Open-Xchanges Web-GUI:
/http://s9.postimage.org/6aohh97ov/iehadjhb.jpg
/
As you can see there is an unamed folder just under Freigaben (Shares).


In Thunderbird:
/http://s12.postimage.org/z0n82k2u5/bjddgefg.jpg/

Now the Folder is "INBOX"...But it is noones Inbox, as the corresponding 
user (amazon e.g.) should be a prefix-folder right before the share.


some output over Telnet:

1 lsub "" "*"
* LSUB () "/" "INBOX"
* LSUB () "/" "INBOX/Amazon"
* LSUB () "/" "INBOX/Bestellung"
* LSUB () "/" "Drafts"
* LSUB () "/" "Sent Items"
* LSUB () "/" "Spam"
* LSUB () "/" "Trash"
* LSUB () "/" "Freigaben/amazon/INBOX"
1 OK Lsub completed.


1 list "" "*"
* LIST (\HasNoChildren) "/" "Trash"
* LIST (\HasNoChildren) "/" "Sent Items"
* LIST (\HasChildren) "/" "INBOX"
* LIST (\HasNoChildren) "/" "INBOX/Amazon"
* LIST (\HasNoChildren) "/" "INBOX/Bestellung"
* LIST (\HasNoChildren) "/" "Spam"
* LIST (\HasNoChildren) "/" "Drafts"
* LIST (\Noselect \HasChildren) "/" "Freigaben/amazon"
* LIST (\Noselect \HasNoChildren) "/" "Freigaben/"
* LIST (\HasNoChildren) "/" "Freigaben/amazon/INBOX"
1 OK List completed.


This looks a bit strange to me:
* LIST (\Noselect \HasNoChildren) "/" "Freigaben/"
But i don't know really if that is the ghostfolder.


finally here's the interesting part in my dovecot.conf:
/
namespace private {
  separator = /
  prefix =
  #location defaults to mail_location.
   inbox = yes
}

namespace  shared {
   separator = /
   prefix = Freigaben/%%n/
   location = maildir:/var/mail/vhosts/%%d/%%n/:INDEX=/var/mail/vhosts/%%d/%%n/
   subscriptions = no
   list = children
   inbox = no
}
/

Any idea how to banish the ghost in the machine?

Thank you very much
Sascha
