Hmm....

(defun message-send-mail-function ()
  "Return suitable value for the variable `message-send-mail-function'."
  (cond ((and (require 'sendmail)
	      (boundp 'sendmail-program)
	      sendmail-program
	      (executable-find sendmail-program))
	 'message-send-mail-with-sendmail)
	((and (locate-library "smtpmail")
	      (boundp 'smtpmail-default-smtp-server)
	      smtpmail-default-smtp-server)
	 'message-smtpmail-send-it)
	((locate-library "mailclient")
	 'message-send-mail-with-mailclient)
	(t
	 (error "Don't know how to send mail.  Please customize `message-send-mail-function'"))))

Maybe you think it's not a possible default, but message.el does use it
by default in some cases, without paying attention to the host OS.
And I think that's right.

In my experience it works, and if it doesn't we should fix it.

I disagree,
