;;; 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,
;; make the init file set it.
(unwind-protect
(save-excursion
(set-buffer (find-file-noselect "site-start.el"))
(setq buffer (current-buffer))
;; Get rid of the line that ran this file.
(if (search-forward "(load \"setaddr\")\n")
