[Dovecot] Public Namespace and INBOX

[Dieter Knopf]

Hello,

i added a existing MAILDIR as a Public Namespace and i can subscribe to
this Namespace without a problem.

I can access every folder except the INBOX. Thunderbird just shows a GREY
"INBOX".

Is there any way to access the INBOX of a maildir?

Thanks
