Did you get any further?

Today I had a strange incident, when one user's account failed to recognize 
the INBOX as mail folder anymore. All subfolders were recognized properly, 
but it was no longer possible to move any mail out of the inbox nor move one 
into it.

Finally I dropped the IMAP resource for this user and recreated it from 
scratch. However, the INBOX was always empty and it behaved like a 
structural node (e.g. like the "shared" node for public folders).

In the end I had to recognize that in the user's .maildir directory  on the 
server the entry "INBOX" was missing in the file "courierimapsubscribed". 
After adding the INBOX again and refreshing the subscriptions on the client, 
the INBOX started to behave normally again.

Actually I have no idea what caused the missing entry for the INBOX in that 
file. The user works only with Kontact and out of pure coincidence I updated 
today from KMail 4.8.1 to 4.8.3 just before I got the report about the 
strange behavior of his INBOX. So I have no idea, whether it was caused by 
the new KMail version or when he created the last folder ...

Did you check the contents of "courierimapsubscribed"?
