Hey, can anyone who has @gmx accouts show me your .gnus, I dont known
how to configure this for send mail, I have something like this:

;; use smtpmail-send-it as the email sending function
(setq send-mail-function 'smtpmail-send-it)
(setq smtpmail-queue-mail t)
(setq message-send-mail-function 'smtpmail-send-it)

(setq smtpmail-auth-login-username "username@gmx.net")
(setq smtpmail-auth-credentials '(("mail.gmx.net" "username@gmx.net"
                                   "PASSWD")))

(setq smtpmail-local-domain "gmx.de")
(setq user-mail-address "username@gmx.net")
(setq smtpmail-queue-dir "~/mail/queued-mail/")

(setq smtpmail-default-smtp-server "mail.gmx.net")
(setq smtpmail-smtp-server "mail.gmx.net")
(setq smtpmail-debug-info t)
