This should read (executable-find sendmail-program).

Until know I didn't look at `mailclient.el' because I though it would
use some Windows or Mac specific functionality.  But AFAICS, it only
delegates to `browse-url'.  I don't use neither Windows nor Mac, so I
don't know if this works more or less out of the box there.

On my system (GNU/Linux), "emacs -Q", (setq send-mail-function
'mailclient-send-it), `M-x mail RET' sends the message to mozilla.

How about the following?

--8<---------------cut here---------------start------------->8---
(defun message-send-mail-function ()
  "Return suitable value for the variable `message-send-mail-function'."
  (cond ((and sendmail-program
              (executable-find sendmail-program))
        ((and (locate-library "smtpmail")
              (require 'smtpmail)
        ((locate-library "mailclient")
         (lambda ()
           (error "Don't know how to send mail.  Please customize 
--8<---------------cut here---------------end--------------->8---

For the unbundled Gnus, we need to test if `smtpmail.el' (XEmacs) and
`mailclient.el' (Emacs 21, XEmacs) is available.

The function `message-send-mail-function' is only to avoid duplicate
