Thx.

It's just an excerpt from

;; post.el --- Use (X?)Emacs(client) as an external editor for mail and news.

#+BEGIN_SRC elisp
(defun post-goto-body ()
  "Go to the beginning of the message body."
  (interactive)
  (goto-char (point-min))
  ;; If the message has header, slide downward.
  (and header-mode (save-match-data (re-search-forward "^$" nil t))
       (next-line 1))
  )
#+END_SRC

Is there a better mode for writing emails (I use mutt calling emacs for

With kind regards,
Stefan
