[Dovecot] Outlook Express / Namespaces

Hi,

I'm planning to switch from courier-imap to dovecot. Everythings seems fine. I adjust the namespaces to avoid client side changes. This works with Thunderbird, but Outlook Express seems to have problmes with the path "INBOX.", that I've configured in the client settings. I can remove that path, but the folders will be sorted under the inbox.

Is there something that I've done wrong? I'm using dovecot 1.0alpha5
