;;; 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.
