NO Mailbox does not exist

[James Treleaven]

I have a few problematic mailboxes (out of approx 40000) that I cannot 
access using 'SELECT INBOX' and I do not understand why that is.  I have 
tried using 'reconstruct', and deleting/recreating these users' 
mailstores but the problem persists.

Is there a semantic difference between 'SELECT INBOX' and 'SELECT 
user/foo' after one has logged in as user 'foo'?  I am using 
'unixhierarchysep: yes'.

I am using cyrus-imapd-2.2.3-83.22 on SuSE 9.1.
