| 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. | |
