使用JavaMail出现的异常

Question

用的是163邮箱，授权已开，在使用JavaMail发邮件，每天开始的几封能正常发送出去，后面会出现以下异常：

源码是：

package test.ceshi;

import java.io.File;
import java.io.IOException;
import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message.RecipientType;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

public class MailTest {


    public static void main(String[] args) throws AddressException, MessagingException, IOException {
        Properties pro = new Properties();
        pro.put("mail.smtp.host", "smtp.163.com");
        pro.put("mail.smtp.auth", "true");
        //pro.setProperty("mail.smtp.starttls.enable", "true");
        Authenticator auth = new Authenticator() {

            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("用户名", "授权码");
            }

        };

        Session session = Session.getInstance(pro, auth);

        MimeMessage msg = new MimeMessage(session);
        msg.setFrom(new InternetAddress("我的邮箱"));
        msg.setRecipients(RecipientType.TO, "发送给的邮箱");
        msg.setSubject("我自己的邮件");
        msg.setContent("我的邮件正文", "text/html;charset=utf-8");

        Transport.send(msg);
    }

}

上网查了方法把上述注释打开则会出现以下异常：

各种方法都试过了还是解决不了，求大神解答，谢谢！

不用太担心,你的发送的邮件被拦截了,163认为你发送的是垃圾邮件
