Hi,

now I tried to send an email with gnus:
------------------------------------------------------------
The debugger said:

  Emacs is about to send an email message, but it has not been
  configured for sending email.  To tell Emacs how to send email:

  - Type ‘mail client’ to start your default email client and
    pass it the message text.

  - Type ‘smtp’ to send mail directly to an "outgoing mail" server.
    (Emacs may prompt you for SMTP settings).

  Emacs will record your selection and will use it thereafter.
  To change it later, customize the option ‘send-mail-function’.


and
Wrong type argument; listp, mailclient-send-it
--------------------------------------------------------------

My gnus.el:

  Reply to mails with matching email address
(setq gnus-posting-styles
       '((address "gottfried <gottfried@posteo.de>")
        ("X-Message-SMTP-Method" "smtp Posteo-posteo.de 465 
gottfried@posteo.de")))


in the gnus manual it says:
;(setq message-send-mail-function 'smtpmail-send-it
;                smtpmail-default-smtp-server "smtp Posteo-posteo.de 465 
gottfried@posteo.de")

but it doesn´t work as well.

I guess there is some code missing.

thanks for help

Gottfried
