It is surprising gnus asks username/password for a  "gmx+AIA", which is
weird. Doesn't make sense. Can it be a bug for trying to
merge/simplify the gnus select methods ? Is there any work, underway to
combine gnus-select-method and gnus-secondary-select-methods ?

Hope all this helps !


For my configuration:
  1. I have no /etc/emacs files.

  2. The $HOME/.emacs.d/init.el file is:

      (setq custom-file "~/customize.el")
      (load custom-file)
      (prefer-coding-system 'utf-8)

  3. The customize.el is attached.

     (custom-set-variables
 ;; custom-set-variables was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
