I don't have any control over the call, though. It looks like this:

(apply
 'call-process-region
 (append
  (list (point-min) (point-max) sendmail-program
	nil errbuf nil "-oi")
  message-sendmail-extra-arguments
 (and (null message-sendmail-f-is-evil)
       (list "-f" (message-sendmail-envelope-from)))
 (if (null message-interactive) '("-oem" "-odb"))
  (if resend-to-addresses
      (list resend-to-addresses)
    '("-t"))))

All I've got to work with is the value of `sendmail-program'. I can't
even stick the script name in `message-sendmail-extra-arguments',
because Python will complain about the "-oi" argument.

All I can think of is providing a separate executable for Windows users,
but I don't know what that executable would look like.

Thanks again,
Eric
