You may want to look more closely at the javadoc for the MimeMultipart class.
It indicates that the class implements a MimePart with a primary content type of "multipart", and a sub-type of "mixed". The documentation also indicates that it is up to us (users) to write sub-classes of MimeMultipart to implement any of the other content sub-type semantics. Thanks to JAF, you do not have to modify sun's original mail.jar to provide support for this mime type.
Conclusion: JavaMail does not support the "related" sub-type, but you can use MimeMultipart as a starting point to build your own implementation.
You may want to look at http://www.imc.org/rfc2387 for a description of the "multipart/related" content type.
