<P>
This class represents a MIME style email message. It implements
the <code>Message</code> abstract class and the <code>MimePart</code>
interface. <p>
Clients wanting to create new MIME style messages will instantiate
an empty MimeMessage object and then fill it with appropriate
attributes and content. <p>
Service providers that implement MIME compliant backend stores may
want to subclass MimeMessage and override certain methods to provide
specific implementations. The simplest case is probably a provider
that generates a MIME style input stream and leaves the parsing of
the stream to this class. <p>
MimeMessage uses the <code>InternetHeaders</code> class to parse and
store the toplevel RFC 822 headers of a message. <p>
<hr><strong>A note on RFC 822 and MIME headers</strong><p>
RFC 822 header fields <strong>must</strong> contain only
US-ASCII characters. MIME allows non ASCII characters to be present
in certain portions of certain headers, by encoding those characters.
RFC 2047 specifies the rules for doing this. The MimeUtility
class provided in this package can be used to to achieve this.
Callers of the <code>setHeader</code>, <code>addHeader</code>, and
<code>addHeaderLine</code> methods are responsible for enforcing
the MIME requirements for the specified headers. In addition, these
header fields must be folded (wrapped) before being sent if they
exceed the line length limitation for the transport (1000 bytes for
SMTP). Received headers may have been folded. The application is
responsible for folding and unfolding headers as appropriate. <p>
