Well, in the meantime, I'm able to use that IMAP account also with
wanderlust, although I haven't used that so far. The needed
configuration for that follows below, for IMAP and SMTP.

One special thing was, that I needed

(setq starttls-extra-arguments '("--insecure"))

because it is true, what the wanderlust error message in *Messages*
said: the host name of the certificate doesn't match.

If that certificate problem is the reason, why gnus doesn't work for me,
for this account - what would be the magic, that I could it make work
with gnus?

That's the wanderlust .wl, use:

;; IMAP
(setq elmo-imap4-default-server "xxx.de"
      elmo-imap4-default-user "yyy@xxx.de"
      elmo-imap4-default-stream-type 'starttls)

;; SMTP
(setq wl-smtp-connection-type 'starttls
      wl-smtp-posting-user "yyy@xxx.de"
      wl-smtp-authenticate-type "cram-md5"
      wl-smtp-posting-server "xxx.de")

(setq wl-from "Mir <yyy@xxx.de>"
      wl-default-folder "%INBOX."
      wl-draft-folder   "%INBOX.Drafts"
      wl-trash-folder   "%INBOX.Trash"
      wl-fcc            "%INBOX.Sent")
