1178 While editing message, type \\[mail-send-and-exit] to send the message and exit.

1184 If `mail-self-blind' is non-nil, a BCC to yourself is inserted

1190 If `mail-archive-file-name' is non-nil, an FCC field with that file name
1193 The normal hook `mail-setup-hook' is run after the message is
1194 initialized. It can add more default fields to the message.
1196 When calling from a program, the first argument if non-nil says
1197 not to erase the existing contents of the `*mail*' buffer.
1199 The second through fifth arguments,
1200 TO, SUBJECT, IN-REPLY-TO and CC, specify if non-nil
1201 the initial contents of those header fields.
1202 These arguments should not have final newlines.
1203 The sixth argument REPLYBUFFER is a buffer which contains an
1204 original message being replied to, or else an action
1205 of the form (FUNCTION . ARGS) which says how to insert the original.
