nil

Documentation

Name of file to write all outgoing messages in, or nil for none.

This is normally an mbox file, but for backwards compatibility may also be a Babyl file. If you are using message-mode to compose messages, customize the variable message-default-mail-headers instead.

Probably introduced at or before Emacs version 17.

Source Code

;; Defined in /usr/src/emacs/lisp/mail/sendmail.el.gz
;; This was a nice idea, for preventing accidental modification of
;; the separator.   But I found it also prevented or obstructed
;; certain deliberate operations, such as copying the separator line
;; up to the top to send myself a copy of an already sent outgoing message
;; and other things.  So I turned it off.  --rms.
