1745 end; see the variable `mail-signature'.
1748 While editing message, type \\[mail-send-and-exit] to send the message and exit.
1750 Various special commands starting with C-c are available in sendmail mode
1751 to move to message header fields:
1754 If `mail-self-blind' is non-nil, a BCC to yourself is inserted
1755 when the message is initialized.
1757 If `mail-default-reply-to' is non-nil, it should be an address (a string);
1758 a Reply-to: field with that address is inserted.
1760 If `mail-archive-file-name' is non-nil, an FCC field with that file name
1763 The normal hook `mail-setup-hook' is run after the message is
1764 initialized. It can add more default fields to the message.
1766 The first argument, NOERASE, determines what to do when there is
1767 an existing modified `*mail*' buffer. If NOERASE is nil, the
1768 existing mail buffer is used, and the user is prompted whether to
1769 keep the old contents or to erase them. If NOERASE has the value
1770 `new', a new mail buffer will be created instead of using the old
1771 one. Any other non-nil value means to always select the old
1772 buffer without erasing the contents.
1774 The second through fifth arguments,
1775 TO, SUBJECT, IN-REPLY-TO and CC, specify if non-nil
1776 the initial contents of those header fields.
1777 These arguments should not have final newlines.
1778 The sixth argument REPLYBUFFER is a buffer which contains an
1779 original message being replied to, or else an action
1780 of the form (FUNCTION . ARGS) which says how to insert the original.
1781 Or it can be nil, if not replying to anything.
1782 The seventh argument ACTIONS is a list of actions to take
