That looks a bit suspicious to me. I think it's better to put the 
configuration for the major mode in Emacs' init file. This is what 
I used to do when I used mutt. First, in .muttrc:

   set editor = emacsclient

(I used emacsclient, which I preferred, but it should work with 
"set editor = emacs" as well).

The best way to do this, I think, is to use `auto-mode-alist`. Put 
this in ~/.emacs.d/init.el:

   (add-to-list 'auto-mode-alist 
   '("mutt-[a-z0-9]+-[0-9]+-[0-9]+.*\\'" . message-mode))

In case that wraps badly, that should be a single line, with a 
space between the dot and `message-mode`.

Note that the regular expression should match the file names that 
mutt creates. I had this work for me for a long long time, but 
it's of course possible that the format changes. You'd have to 
adjust the regexp then.

Note also that this puts mutt messages into `message-mode`, which 
I prefer, but you can use `text-mode` as well.

That should work, it used to work for me. (I switched to mu4e, but 
I've been using mutt as a backup until quite recently, so the 
setup has been tested with Emacs 26).
