Mail::Message#add_mime_version

Creates a new empty Mime Version field and inserts it in the correct order
into the Header.  The MimeVersion object will automatically generate
set itself to '1.0' if you try and encode it or output it to_s without
specifying a version yourself.

It will preserve any date you specify if you do.
