565 If `mail-self-blind' is non-nil, a BCC to yourself is inserted

568 If `mail-default-reply-to' is non-nil, it should be an address (a string);
569 a Reply-to: field with that address is inserted.
571 If `mail-archive-file-name' is non-nil, an FCC field with that file name
574 If `mail-setup-hook' is bound, its value is called with no arguments
575 after the message is initialized. It can add more default fields.
577 When calling from a program, the second through fifth arguments
578 TO, SUBJECT, IN-REPLY-TO and CC specify if non-nil
579 the initial contents of those header fields.
580 These arguments should not have final newlines.
581 The sixth argument REPLYBUFFER is a buffer whose contents
582 should be yanked if the user types C-c C-y.
583 The seventh argument ACTIONS is a list of actions to take
584 if/when the message is sent. Each action looks like (FUNCTION . ARGS);
585 when the message is sent, we apply FUNCTION to ARGS.
