1441 The value is t if the message was newly initialized; otherwise, nil.
1443 Optionally, the signature file `mail-signature-file' can be inserted at the
1444 end; see the variable `mail-signature'.
1447 While editing message, type \\[mail-send-and-exit] to send the message and exit.
1449 Various special commands starting with C-c are available in sendmail mode
1450 to move to message header fields:
1453 If `mail-self-blind' is non-nil, a BCC to yourself is inserted
1454 when the message is initialized.
1456 If `mail-default-reply-to' is non-nil, it should be an address (a string);
1457 a Reply-to: field with that address is inserted.
1459 If `mail-archive-file-name' is non-nil, an FCC field with that file name
1462 The normal hook `mail-setup-hook' is run after the message is
1463 initialized. It can add more default fields to the message.
1465 When calling from a program, the first argument if non-nil says
1466 not to erase the existing contents of the `*mail*' buffer.
1468 The second through fifth arguments,
1469 TO, SUBJECT, IN-REPLY-TO and CC, specify if non-nil
1470 the initial contents of those header fields.
1471 These arguments should not have final newlines.
1472 The sixth argument REPLYBUFFER is a buffer which contains an
1473 original message being replied to, or else an action
1474 of the form (FUNCTION . ARGS) which says how to insert the original.
1475 Or it can be nil, if not replying to anything.
1476 The seventh argument ACTIONS is a list of actions to take
1477 if/when the message is sent. Each action looks like (FUNCTION . ARGS);
1478 when the message is sent, we apply FUNCTION to ARGS.
