1654 The value is t if the message was newly initialized; otherwise, nil.

1664 \\{mail-mode-map}
1665
1666 If `mail-self-blind' is non-nil, a BCC to yourself is inserted
1667 when the message is initialized.
1668
1669 If `mail-default-reply-to' is non-nil, it should be an address (a string);
1670 a Reply-to: field with that address is inserted.
1671
1672 If `mail-archive-file-name' is non-nil, an FCC field with that file name
1673 is inserted.
1674
1675 The normal hook `mail-setup-hook' is run after the message is
1676 initialized. It can add more default fields to the message.
1677
1678 The first argument, NOERASE, determines what to do when there is
1679 an existing modified `*mail*' buffer. If NOERASE is nil, the
1680 existing mail buffer is used, and the user is prompted whether to
1681 keep the old contents or to erase them. If NOERASE has the value
1682 `new', a new mail buffer will be created instead of using the old
1683 one. Any other non-nil value means to always select the old
1684 buffer without erasing the contents.
1685
1686 The second through fifth arguments,
1687 TO, SUBJECT, IN-REPLY-TO and CC, specify if non-nil
1688 the initial contents of those header fields.
1689 These arguments should not have final newlines.
1690 The sixth argument REPLYBUFFER is a buffer which contains an
1691 original message being replied to, or else an action
1692 of the form (FUNCTION . ARGS) which says how to insert the original.
1693 Or it can be nil, if not replying to anything.
1694 The seventh argument ACTIONS is a list of actions to take
1695 if/when the message is sent. Each action looks like (FUNCTION . ARGS);
1696 when the message is sent, we apply FUNCTION to ARGS.
1697 This is how Rmail arranges to mark messages `answered'."
