| 1744 | "Edit a message to be sent. Prefix arg means resume editing (don't erase). |
| 1745 | When this function returns, the buffer `*mail*' is selected. |
| 1746 | The value is t if the message was newly initialized; otherwise, nil. |
| 1747 | |
| 1748 | Optionally, the signature file `mail-signature-file' can be inserted at the |
| 1749 | end; see the variable `mail-signature'. |
| 1750 | |
| 1751 | \\<mail-mode-map> |
| 1752 | While editing message, type \\[mail-send-and-exit] to send the message and exit. |
| 1753 | |
| 1754 | Various special commands starting with C-c are available in sendmail mode |
| 1755 | to move to message header fields: |
| 1756 | \\{mail-mode-map} |
| 1757 | |
| 1758 | If `mail-self-blind' is non-nil, a BCC to yourself is inserted |
| 1759 | when the message is initialized. |
| 1760 | |
| 1761 | If `mail-default-reply-to' is non-nil, it should be an address (a string); |
| 1762 | a Reply-to: field with that address is inserted. |
| 1763 | |
| 1764 | If `mail-archive-file-name' is non-nil, an FCC field with that file name |
| 1765 | is inserted. |
| 1766 | |
| 1767 | The normal hook `mail-setup-hook' is run after the message is |
| 1768 | initialized. It can add more default fields to the message. |
| 1769 | |
| 1770 | The first argument, NOERASE, determines what to do when there is |
| 1771 | an existing modified `*mail*' buffer. If NOERASE is nil, the |
| 1772 | existing mail buffer is used, and the user is prompted whether to |
| 1773 | keep the old contents or to erase them. If NOERASE has the value |
| 1774 | `new', a new mail buffer will be created instead of using the old |
| 1775 | one. Any other non-nil value means to always select the old |
| 1776 | buffer without erasing the contents. |
| 1777 | |
| 1778 | The second through fifth arguments, |
| 1779 | TO, SUBJECT, IN-REPLY-TO and CC, specify if non-nil |
| 1780 | the initial contents of those header fields. |
| 1781 | These arguments should not have final newlines. |
| 1782 | The sixth argument REPLYBUFFER is a buffer which contains an |
| 1783 | original message being replied to, or else an action |
| 1784 | of the form (FUNCTION . ARGS) which says how to insert the original. |
| 1785 | Or it can be nil, if not replying to anything. |
| 1786 | The seventh argument ACTIONS is a list of actions to take |
| 1787 | if/when the message is sent. Each action looks like (FUNCTION . ARGS); |
| 1788 | when the message is sent, we apply FUNCTION to ARGS. |
| 1789 | This is how Rmail arranges to mark messages `answered'." |
