I also have msmtp and here is my set of .emacs configs

  (setq sendmail-program "/usr/bin/msmtp")
  (setq mail-specify-envelope-from t)
  (setq message-sendmail-envelope-from 'header)
  (setq mail-envelope-from 'header)
  (setq send-mail-function 'message-send-mail-with-sendmail)

There is a line for it in my .mailrc:

  set sendmail="/usr/bin/msmtp"

I /think/ that's all I have about the sending of mails and it works
fine. (plus the msmtp configs of course).

Best regards
