subclasses. MIMENonMultipart: Base class for non-multipart/* content type subclass specializations, e.g. image/gif. This class overrides attach() which raises an exception, since it makes no sense to attach a subpart to e.g. an image/gif message. MIMEMultipart: Base class for multipart/* content type subclass specializations, e.g. multipart/mixed. Does little more than provide a useful constructor.
