696 "Edit a message to be sent. Prefix arg means resume editing (don't erase).
697 When this function returns, the buffer `*mail*' is selected.
698 The value is t if the message was newly initialized; otherwise, nil.
700 By default, the signature file `~/.signature' is inserted at the end;
701 see the variable `mail-signature'.
704 While editing message, type \\[mail-send-and-exit] to send the message and exit.
706 Various special commands starting with C-c are available in sendmail mode
707 to move to message header fields:
710 If `mail-self-blind' is non-nil, a BCC to yourself is inserted
711 when the message is initialized.
713 If `mail-default-reply-to' is non-nil, it should be an address (a string);
714 a Reply-to: field with that address is inserted.
716 If `mail-archive-file-name' is non-nil, an FCC field with that file name
719 If `mail-setup-hook' is bound, its value is called with no arguments
720 after the message is initialized. It can add more default fields.
722 When calling from a program, the second through fifth arguments
723 TO, SUBJECT, IN-REPLY-TO and CC specify if non-nil
724 the initial contents of those header fields.
725 These arguments should not have final newlines.
726 The sixth argument REPLYBUFFER is a buffer whose contents
727 should be yanked if the user types C-c C-y.
728 The seventh argument ACTIONS is a list of actions to take
729 if/when the message is sent. Each action looks like (FUNCTION . ARGS);
730 when the message is sent, we apply FUNCTION to ARGS.
731 This is how Rmail arranges to mark messages `answered'."
