Can access everything but Inbox on my IMAP server

[levander]

After having spent an hour figuring out that you have to set an NNTP
server even if you just want to read your mail, now I can read all my
mail, except for what's in my Inbox.

I'm running Ubuntu Feisty, dovecot as an IMAP server, and Gnus v.
5.11.

I'm using the Maildir format.  One thing I noticed is that if I go
down into ~/Maildir, there's a directory, whose name starts with a
dot, for every folder that I see in other mail readers.  And, each of
these directories have a subdirectory named cur.  Every directory that
is except for .INBOX.  E.g., there's a .Trash/cur, a .Sent/cur, etc.
But, there's no .INBOX/cur.  From looking at the contents, it looks
like Inbox's cur is right in Maildir - it's at ~/Maildir/cur.

Is this the problem?  Do I have to somehow tell gnus that Inbox is
structured a little differently on the filesystem?  I can't imagine
that I would have to.  I imagine gnus is going to dovecot, and it's
dovecot reading off the filesystem...
