Some chinese words problem in Javamail via MS Exchange Server

Question

Dear All
I have a Javamail problem.
When I use Javamail to send email via MS Exchange Server, there are some chinese words will become corrupt code and not all chinese words. i.e ("��", The code in big5 is "F9 D6").
If I use Javamail + Linux SendMail, this problem will not happen. All chinese words will display correctly by the same program. Anybody else know why and how to resolve it?
The following code is part of my program.
String mailHost = "192.168.1.255";
String subject = "TESTING WORD ��";
String mailBody = "TESTING WORD ��";
Properties props = new Properties();
props.put("mail.smtp.host", mailHost);
Session session = Session.getDefaultInstance(props, null);
MimeMessage msg = new MimeMessage(session);
msg.setFrom(from);
msg.setRecipients(Message.RecipientType.TO, addressTO);
msg.setSubject("=?big5?B?" + enc.encode(subject.getBytes()) +"?=");
msg.setContent(mailBody, "text/html; charset=big5");
Transport.send(msg);

clearly looks like an MS Exchange problem to me. May be they are not encoding the 8 bit data properly? So, you are using MS Exchange to send it and which client do you use to read the mail sent?
