您正在创建发送邮件，而不是保存您收到的邮件，对吗？

JavaMail FAQ有sample code for creating a multipart/related message：

    Multipart multipart = new MimeMultipart("related");

    MimeBodyPart htmlPart = new MimeBodyPart();
    // messageBody contains html that references image
    // using something like <img src="cid:XXX"> where
    // "XXX" is an identifier that you make up to refer
    // to the image
    htmlPart.setText(messageBody, "utf-8", "html");
    multipart.addBodyPart(htmlPart);

    MimeBodyPart imgPart = new MimeBodyPart();
    // imageFile is the file containing the image
    imgPart.attachFile(imageFile);
    // or, if the image is in a byte array in memory, use
    // imgPart.setDataHandler(new DataHandler(
    //      new ByteArrayDataSource(bytes, "image/whatever")));

    // "XXX" below matches "XXX" above in html code
    imgPart.setContentID("<XXX>");
    multipart.addBodyPart(imgPart);

    message.setContent(multipart);
