newbie question: trouble with mail splitting

[Karl]

Hello gnus-list,

i'm happy to use gnus for reading and writing mails.
Now i want to split mails, but i do not understand how it works.

here is my config, but it doesnt work. All mail goes to mail.misc.
Does anyone knows what to do?

;; split
;; client-side imap splitting ermöglichen
(gnus-group-split-setup t)
(setq nnimap-split-download-body t)
(setq nnmail-crosspost nil)
(setq nnmail-split-methods 'nnmail-split-fancy)
(setq nnmail-split-fancy
      '(|
        ;;(: spam-split 'spam-use-regex-headers)
        (to "emacs-orgmode@gnu.org" "nnmaildir+Lokal:OrgDigest")
        (from ".*n3.nabble.com" "nnmaildir+Lokal:notmuch")
        (from ".*pinterest.com" "nnmaildir+Lokal:Pinterest")
        (subject "^FRITZ!.*" "nnmaildir+Lokal:fritz")
        (from "forum@papyrus.de" "nnmaildir+Lokal:Papyrus")
        ;;(: spam-split)
        ("mail.misc")
        ))

;; initialisiere split
(setq gnus-group-split-setup t)
(setq nnmail-pre-get-new-mail-hook '(gnus-group-split-update))

(setq gnus-secondary-select-methods '(
(nnimap "GMail"
                                              (nnimap-address "imap.gmail.com")
                                              (nnimap-server-port "imaps")
                                              (nnimap-user "xxx@googlemail.com")
                                              (nnimap-stream ssl)
                                              (nnimap-split-methods 
'nnmail-split-fancy)
                                              (get-new-mail t)
                                              (nnir-search-engine imap)
                                              )
                                              ))

My system is Linux Mint 19.1
Emacs 26.2
