gnus and imap

[Fabian Yamaguchi]

hi list!
I've switched to imap recently and I cannot figure out how to configure gnus to 
split my mails
correctly.
Here's the part of my ~/.gnus which I wrote:


========================
(setq gnus-secondary-select-methods 
      '((nnimap "localhost")
))


(setq nnimap-split-inbox "INBOX")

(setq nnimap-split-rule
        '(("INBOX.belug"
        "List-Id: Die Mailingliste der BeLUG (Berliner Linux User Group) 
<linux-l.mlists.in-berlin.de>")
        
        ("INBOX.gtk"
        "List-Id: General discussion of GTK+ <gtk-list.gnome.org>")
        
        ("INBOX.emacs"
        "List-Id: Users list for the GNU Emacs text editor 
<help-gnu-emacs.gnu.org>")
        
        ("INBOX.ccc"
        "List-Id: CCC Diskussionsliste <debate.lists.ccc.de>")
        
        ("INBOX.private" "")
        ))

======================

What this is supposed to do is take all mail from my inbox and sort out all 
mail coming from
mailing-lists. Everything else then goes into INBOX.private.
When I start gnus, it seems to sort my mail but when I try to access it, I'm 
told the mailbox doesn't
exist. I've tried to subscribe to several "groups" for example nnimap:emacs, 
nnimap:INBOX:emacs,
INBOX:emacs, INBOX.emacs etc, etc but they all give me the same "the mailbox 
doesn't
exist"-error-message.

Please tell me what I'm doing wrong.
