无法使用JAVA MAIL API在Yahoo中回复邮件

Question

同一段代码在Gmail中可以成功地用于回复邮件，但是在yahoo中，我遇到了错误。

这是我尝试过的代码

Message[] messages2 = folder.search(new FlagTerm(new Flags(Flags.Flag.SEEN), false));
Message msg =  messages2[i];
 System.out.println("\n 1st ===> setup Mail Server Properties..");
                                        mailServerProperties = System.getProperties();
                                        mailServerProperties.put("mail.smtp.port", "587");
                                        mailServerProperties.put("mail.smtp.auth", "true");
                                        mailServerProperties.put("mail.smtp.starttls.enable", "true");
System.out.println("Mail Server Properties have been setup successfully..");
                                        getMailSession = Session.getDefaultInstance(mailServerProperties, null);

                                        Message replyMessage = new MimeMessage(getMailSession);
                                          replyMessage = (MimeMessage) msg.reply(false);
                                          replyMessage.setFrom(new InternetAddress(to));
                                          replyMessage.setText("Thanks");
                                          replyMessage.setReplyTo(msg.getReplyTo());

                                          // Send the message by authenticating the SMTP server
                                          // Create a Transport instance and call the sendMessage
                                          Transport t = session.getTransport("smtp");
                                          try {
                                     //connect to the smpt server using transport instance
                                     //change the user and password accordingly 
                                         t.connect("smtp.mail.yahoo.com",table_user, table_pass);
                                         t.sendMessage(replyMessage,
                                                replyMessage.getAllRecipients());
                                          } finally {
                                             t.close();
                                          }
                                          System.out.println("message replied successfully ....");

我得到的错误：

[请指出正确的方向，这是我做错了。

Yahoo邮件服务器不喜欢您的回复邮件收件人之一。尝试启用JavaMail debug output，您可能会得到更多有关错误的信息。

还请注意，您正在使用MimeMessage构造函数创建ReplyMessage，然后将该值扔掉并将其分配给Reply方法的返回值。您可以摆脱对构造函数的调用，该调用不执行任何操作。
