While editing message, type \\[mail-send-and-exit] to send the message and exit.

Various special commands starting with C-c are available in sendmail mode
to move to message header fields:
\\{mail-mode-map}

If `mail-self-blind' is non-nil, a BCC to yourself is inserted
when the message is initialized.

If `mail-default-reply-to' is non-nil, it should be an address (a string);
a Reply-to: field with that address is inserted.

If `mail-archive-file-name' is non-nil, an FCC field with that file name
is inserted.

 These arguments should not have final newlines.
The sixth argument REPLYBUFFER is a buffer whose contents
 should be yanked if the user types C-c C-y.
The seventh argument ACTIONS is a list of actions to take
 if/when the message is sent.  Each action looks like (FUNCTION . ARGS);
 when the message is sent, we apply FUNCTION to ARGS.
 This is how Rmail arranges to mark messages `answered'."
