- The {msg} item of Message object does no longer represent actual content: Original string representation will be kept as far as possible.
- {msg_as_string} was splitted to {_head} (MIME::Head entity) and {_body} (body as string).  Accessors are head(), header_as_string(), body_as_string() and as_string().
- For now don't access to {msg}, {_head} and {_body} items directly: Use as_entity() and methods above.
- add_header(), delete_header() or replace_header() should be used to modify {_head}.  get_header() may be used to get header fields (only at the top level of structure).
- {orig_msg} item was replaced by {orig_msg_as_string} to prevent reencoding, too.
- To get message ID, sender and so on, use items {message_id}, {sender} and so on of objects, not using get_header() etc.
- See also POD.

ToDo: Some components (probably bulk.pl etc.) still reencode contents.
