And here's the same for choosing the identity when forwarding a mail:

;; Choose the identity used to forward a mail
(defun schnouki/notmuch-mua-forward-message ()
  (interactive)
  (let* ((from (ido-completing-read "Sender identity: " schnouki/mua-identities
				    nil nil nil nil (car schnouki/mua-identities)))
	 (address-components (mail-extract-address-components from))
	 (user-full-name (car address-components))
	 (user-mail-address (cadr address-components)))
    (notmuch-mua-forward-message)))

(people who don't use or like ido may want to replace
ido-completing-read with completing-read)

If anyone is interested, I have some more useful snippets available on
https://github.com/Schnouki/dotfiles/blob/master/emacs/init-50-mail.el#L232:
- function to choose a signature according to the From header
- function to choose the sender identity according to the To header
  (useful for replying to work e-mails using your work address, or for
  replying to a ML with a subscribed address that won't be rejected)
- function to change the SMTP server that will be used for sending the
  mail according to the From header

It seriously lacks documentation so don't hesitate to ask if you have
any problem with it :)

Regards,
