25 ;;; Commentary:
27 ;; If neither sendmail nor Emacs knows what host address to use
28 ;; for this machine, ask for it, and save it in site-start.el
29 ;; so we won't have to ask again.
31 ;; This uses a heuristic about the output from sendmail
32 ;; which may or may not really work. We will have to find
33 ;; out by experiment.
35 ;;; Code:
37 (or mail-host-address
38 (let (sendmail-configured)
39 (with-temp-buffer " mail-host-address"
