Re: Gnus: How to easily change "From:" from the default to a second account's address?

[Philipp Haselwarter <philipp.haselwarter@gmx.de>]

I often find myself wanting to change the From: after opening the
message; this allows picking one of your accounts:

#+begin_src emacs-lisp
(defcustom my-smtp-accounts nil
  "*list of available smtp accounts"
  :group 'smtpmail
  :type '(repeat alist))

(defun my-pick-smtp ()
  (interactive)
  (setq user-mail-address
        (let ((f (if (functionp 'ido-completing-read)
                     'ido-completing-read
                   completing-read)))
          (funcall f "Which smtp acc:" (mapcar 'cadr my-smtp-accounts))))
  (save-excursion
    (save-restriction
      (message-narrow-to-headers-or-head)
      (message-remove-header "From")
      (goto-char (point-max))
      (insert "From: " (message-make-from) "\n"))))

#+end_src
