It implements the <code>BodyPart</code> abstract class and the <code>MimePart</code> interface. MimeBodyParts are contained in <code>MimeMultipart</code> objects. <p> MimeBodyPart uses the <code>InternetHeaders</code> class to parse and store the headers of that body part. <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><P><P><DL><DT><B>Author:</B></DT> <DD>John Mani, Bill Shannon</DD><DT><B>See Also:</B><DD><A
