By default, creates a multipart/mixed message, with proper
Content-Type: and MIME-Version: headers.
_subtype is the subtype of the multipart content type, defaulting to
`mixed'.
boundary is the multipart boundary string. By default it is
calculated as needed.
_subparts is a sequence of initial subparts for the multipart. It
must be possible to convert this sequence to a list. You can always
attach new subparts to the message by using the attach() method.
Additional parameters for the Content-Type: header are taken from the
keyword arguments (or passed into the _params argument).
