1662 The value is t if the message was newly initialized; otherwise, nil.
1664 Optionally, the signature file `mail-signature-file' can be inserted at the
1665 end; see the variable `mail-signature'.
1668 While editing message, type \\[mail-send-and-exit] to send the message and exit.
1670 Various special commands starting with C-c are available in sendmail mode
1671 to move to message header fields:
1674 If `mail-self-blind' is non-nil, a BCC to yourself is inserted
1675 when the message is initialized.
1677 If `mail-default-reply-to' is non-nil, it should be an address (a string);
1678 a Reply-to: field with that address is inserted.
1680 If `mail-archive-file-name' is non-nil, an FCC field with that file name
1683 The normal hook `mail-setup-hook' is run after the message is
1684 initialized. It can add more default fields to the message.
1686 The first argument, NOERASE, determines what to do when there is
1687 an existing modified `*mail*' buffer. If NOERASE is nil, the
1688 existing mail buffer is used, and the user is prompted whether to
1689 keep the old contents or to erase them. If NOERASE has the value
1690 `new', a new mail buffer will be created instead of using the old
1691 one. Any other non-nil value means to always select the old
1692 buffer without erasing the contents.
1694 The second through fifth arguments,
1695 TO, SUBJECT, IN-REPLY-TO and CC, specify if non-nil
1696 the initial contents of those header fields.
1697 These arguments should not have final newlines.
1698 The sixth argument REPLYBUFFER is a buffer which contains an
1699 original message being replied to, or else an action
1700 of the form (FUNCTION . ARGS) which says how to insert the original.
1701 Or it can be nil, if not replying to anything.
1702 The seventh argument ACTIONS is a list of actions to take
1703 if/when the message is sent. Each action looks like (FUNCTION . ARGS);
1704 when the message is sent, we apply FUNCTION to ARGS.
1705 This is how Rmail arranges to mark messages `answered'."
