+
+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.
+
+The normal hook `mail-setup-hook' is run after the message is
+initialized. It can add more default fields to the message.
+
+The first argument, NOERASE, determines what to do when there is
+an existing modified `*mail*' buffer. If NOERASE is nil, the
+existing mail buffer is used, and the user is prompted whether to
+keep the old contents or to erase them. If NOERASE has the value
+`new', a new mail buffer will be created instead of using the old
+one. Any other non-nil value means to always select the old
+buffer without erasing the contents.
+
+The second through fifth arguments,
+ TO, SUBJECT, IN-REPLY-TO and CC, specify if non-nil
+ the initial contents of those header fields.
+ These arguments should not have final newlines.
+The sixth argument REPLYBUFFER is a buffer which contains an
+ original message being replied to, or else an action
+ of the form (FUNCTION . ARGS) which says how to insert the original.
+ Or it can be nil, if not replying to anything.
+The seventh argument ACTIONS is a list of actions to take
