1661 end; see the variable `mail-signature'.
1664 While editing message, type \\[mail-send-and-exit] to send the message and exit.
1666 Various special commands starting with C-c are available in sendmail mode
1667 to move to message header fields:
1670 If `mail-self-blind' is non-nil, a BCC to yourself is inserted
1671 when the message is initialized.
1673 If `mail-default-reply-to' is non-nil, it should be an address (a string);
1674 a Reply-to: field with that address is inserted.
1676 If `mail-archive-file-name' is non-nil, an FCC field with that file name
1679 The normal hook `mail-setup-hook' is run after the message is
1680 initialized. It can add more default fields to the message.
1682 The first argument, NOERASE, determines what to do when there is
1683 an existing modified `*mail*' buffer. If NOERASE is nil, the
1684 existing mail buffer is used, and the user is prompted whether to
1685 keep the old contents or to erase them. If NOERASE has the value
1686 `new', a new mail buffer will be created instead of using the old
1687 one. Any other non-nil value means to always select the old
1688 buffer without erasing the contents.
1690 The second through fifth arguments,
1691 TO, SUBJECT, IN-REPLY-TO and CC, specify if non-nil
1692 the initial contents of those header fields.
1693 These arguments should not have final newlines.
1694 The sixth argument REPLYBUFFER is a buffer which contains an
1695 original message being replied to, or else an action
1696 of the form (FUNCTION . ARGS) which says how to insert the original.
1697 Or it can be nil, if not replying to anything.
1698 The seventh argument ACTIONS is a list of actions to take
1699 if/when the message is sent. Each action looks like (FUNCTION . ARGS);
1700 when the message is sent, we apply FUNCTION to ARGS.
1701 This is how Rmail arranges to mark messages `answered'."
