How to make Emacs Gnus to get new mails automatically?

Question

I try to fetch new mails with Gnus, but it doesn't work. I tried following options in my .emacs file:

;(setq gnus-demon-timestep 10)
(gnus-demon-add-handler 'gnus-group-get-new-news 1 nil)
;(gnus-demon-add-handler 'gnus-demon-scan-mail 1 nil)
;(gnus-demon-add-handler 'gnus-demon-scan-news 1 nil)
(gnus-demon-init)

I tried to add each of the 3 handlers, and put t instead of nil, but it didn't work. If I press g or run M-x gnus-group-get-new-news manually Gnus does fetchs new mails. I checked gnus-demon-handlers and it indeed says: gnus-demon-handlers's value is ((gnus-group-get-new-news 1 nil)) but it doesn't fetch mails automatically.

Try moving (gnus-demon-init) above the rest. The functions don't exist until that the demon is initialized.

e.g.

(add-hook 'gnus-startup-hook
  '(lambda ()
     (gnus-demon-init)
     (setq gnus-demon-timestep 60)  ;; each timestep is 60 seconds
     ;; Check for new mail every 1 timestep (1 minute)
     (gnus-demon-add-handler 'gnus-demon-scan-news 1 t)

     ;; Don't crash gnus if disconnected
     (defadvice gnus-demon-scan-news (around gnus-demon-timeout activate)
       "Timeout for Gnus."
       (with-timeout
       (120 (message "Gnus timed out."))
     ad-do-it))))
