+;;; Commentary:
+
+;; If neither sendmail nor Emacs knows what host address to use
+;; for this machine, ask for it, and save it in site-start.el
+;; so we won't have to ask again.
+
+;; This uses a heuristic about the output from sendmail
+;; which may or may not really work.  We will have to find
+;; out by experiment.
+
+;;; Code:
+
+(or mail-host-address
+    (let (sendmail-configured)
+      (with-temp-buffer " mail-host-address"
+	(call-process sendmail-program nil t nil "-bv" "root")
+	(goto-char (point-min))
+	(setq sendmail-configured (looking-at "root@")))
+      (or sendmail-configured
+	  (let (buffer)
+		(setq mail-host-address
+		      (read-string "Specify your host's fully qualified domain name: ")))
+	  ;; Create an init file, and if we just read mail-host-address,
