I would like to use Gnus retrieving emails:

My config:

(add-to-list 'gnus-secondary-select-methods
             '(nnimap "gmx"
                      (nnimap-address "imap.gmx.com")
                      (nnimap-server-port 993)
                      (nnimap-stream ssl)
                      (nnir-search-engine imap)))

Password info is put in: ~/.authinfo.gpg

The imap error:
