[Dovecot] 1.0rc25: double INBOX folder (weird)

[Jeff Mitchell]

Or, you're hitting some kind of bug in Tbird like what I described in my 
earlier post.

I'd try deleting Thunderbird's on-disk cache of your IMAP folders.  Dovecot 
may be working just fine, and Tbird may not be handling its out-of-date cache 
correctly (which it doesn't).
