Unable to properly configure Maildir with Gnus ?

[Ashish Shukla]

Hi,

I've just restarted using Gnus. I'm using "fetchmail" to fetch my
mails and push it to local MTA, which delivers incoming mails to "~/
Maildir" . I'm also using Mutt and Kmail, both configured with Maildir
backends. All my mail folders are stored in "~/mail" as "Maildir", and
are shared between Mutt and Kmail. Now I wanted to use Gnus as well,
so I wrote following basic ".gnus":

-- begin .gnus --
(setq mail-source '((maildir)))
(setq gnus-select-method '(nnnil))
(setq gnus-secondary-select-methods '((nnmaildir "" (directory "~/
mail"))))
(setq nnmail-split-methods
          '(("sent-mail" "^From:.*wahjava@")
            ("lists" "^List-Id: ")
            ("inbox") ("")))
-- end .gnus --

Now with above .gnus I'm able to see all my mail folders and mails in
Gnus, but I'm not able to view any new mail delivered in "~/Maildir/
new"  by fetchmail.

Any ideas what I'm missing above ? I'm using Gnus v5.11 in GNU Emacs
22.0.990.1 in Fedora 7 (amd64) .

Thanks in advance.
