By default, creates a multipart/mixed message, with proper

_subtype is the subtype of the multipart content type, defaulting to

`mixed'.

boundary is the multipart boundary string. By default it is

_subparts is a sequence of initial subparts for the payload. It
|

must be an iterable object, such as 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).
