Java邮件创建DSN（交付状态通知）

Question

I want to create DSN (delivered status notification) and send back to sender. I use MimeMulitPartReport and add 3 part of body. However, it does not work. In the recipient side, it does not show a human readable message and DSN information. I can't figure out, what's wrong in my code.

Thank you

I use JavaMail 1.4.5 with DSN extension http://www.oracle.com/technetwork/java/javamail/index-141777.html :

private MimeMessage dsnEmail() throws MessagingException {
    MimeMessage msg = new MimeMessage(mailSession);
    MultipartReport multipart = new MultipartReport(
            HUMAN_READABLE_MSG,
            new DeliveryStatus(),
            originalEmail
    );
    msg.setContent(multipart);
    msg.setSubject("Delivery Status Notification (failure)");
    msg.setRecipient(Message.RecipientType.TO, originalEmail.getSender());
    return msg;
}

with this maven import :

<dependency>
    <groupId>com.sun.mail</groupId>
    <artifactId>dsn</artifactId>
    <version>1.4.5</version>
</dependency>

I hope it helps
