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. | |
30 | ||
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. | |
