利用gmail发送邮件代码

现在能使用pop3/smtp的邮箱不多了，而且还需要手动设置，gmail邮箱就不错，他的端口号和其他的邮箱不一样，发信的端口号是465，这段代码是我从网上找到的，感觉很简洁，只是没有附件功能，不过还是可以满足需求的。
package com.util;

import java.security.Security;
import java.util.Date;
import java.util.Properties;

import javax.mail.Authenticator;
import javax.mail.Message;
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.MimeMessage;

public class GmailSender {

public void sender(String to,String title,String text) throws AddressException, MessagingException {
   Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
   final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
   // Get a Properties object
   Properties props = System.getProperties();
   props.setProperty("mail.smtp.host", "smtp.gmail.com");
   props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);
   props.setProperty("mail.smtp.socketFactory.fallback", "false");
   props.setProperty("mail.smtp.port", "465");
   props.setProperty("mail.smtp.socketFactory.port", "465");
   props.put("mail.smtp.auth", "true");
   final String username = "你要利用发信的gmail邮箱";
   final String password = "密码";
   Session session = Session.getDefaultInstance(props, new Authenticator(){
      protected PasswordAuthentication getPasswordAuthentication() {
          return new PasswordAuthentication(username, password);
      }});

       // -- Create a new message --
   Message msg = new MimeMessage(session);

   // -- Set the FROM and TO fields --
   msg.setFrom(new InternetAddress(username));
   msg.setRecipients(Message.RecipientType.TO,
     InternetAddress.parse(to,false));//收件人地址
   msg.setSubject(title);//邮件标题
   msg.setText(text);//邮件正文
   msg.setSentDate(new Date());
   Transport.send(msg);

   System.out.println("Message sent.");
}
}

当使用非gmail域名的gmail邮箱作为smtp发送电子邮件时报异常：
