用jsp+javamail做发邮件的小程序：

登陆页面JavaMail.html如下：



<html>

<head>

	<title>JavaMail.html</title>

<meta http-equiv="Content-Type" content="text/html;charset=GB2312">

</head>

<body>



<h2>利用JavaMail来发送电子邮件</h2>



<form name="form" method="POST" action="JavaMail.jsp">

	<p>寄信人：<input type="text" name="From" size="35" maxlength="35"></p>

	<p>收信人：<input type="text" name="To" size="35" maxlength="35"></p>

	<p>主题: <input type="text" name="Subject" size="35" maxlength="35"></p>

	<p>内容：<textarea name="Message" cols="30" rows="5"></textarea></p>

	<input type="submit" value="发送">

	<input type="reset" value="清除">

</form>

</body>

</html>

邮件发送的处理页面JavaMail.jsp如下：



<%@ page import="javax.mail.*" %>

<%@ page import="javax.mail.internet.*" %>

<%@ page import="javax.activation.*" %>

<%@ page import="java.util.*,java.io.*" %>

<%@ page contentType="text/html;charset=GB2312" %>



<html>

<head>

  <title>JavaMail.jsp</title>

</head>

<body>



<h2>利用JavaMail来传送电子邮件 </h2>

<%



	InternetAddress[] address = null;



	request.setCharacterEncoding("GB2312");



	Authenticator auth = (Authenticator)

	new com.yang.PopupAuthenticator("251887663","8888");



	String mailserver   = "smtp.qq.com";

	String From         = request.getParameter("From");

	String to           = request.getParameter("To");

	String Subject      = request.getParameter("Subject");

    String messageText  = request.getParameter("Message");



    boolean sessionDebug = false;

	

try {



  // 设定所要用的Mail 服务器和所使用的传输协议

  java.util.Properties props = System.getProperties();

  props.put("mail.host",mailserver);

  props.put("mail.transport.protocol","smtp");

  

  // 产生新的Session 服务

  javax.mail.Session mailSession = javax.mail.Session.getDefaultInstance(props,auth);

  mailSession.setDebug(sessionDebug);

  Message msg = new MimeMessage(mailSession);

  

  // 设定传送邮件的发信人

  msg.setFrom(new InternetAddress(From));

  

  // 设定传送邮件至收信人的信箱

  address = InternetAddress.parse(to,false);

  msg.setRecipients(Message.RecipientType.TO, address);

  

  // 设定信中的主题 

  msg.setSubject(Subject);

  // 设定送信的时间

  msg.setSentDate(new Date());

  

  // 设定传送信的MIME Type

  msg.setText(messageText);



  // 送信

  Transport.send(msg);



  out.println("邮件已顺利传送");

	

}

    catch (MessagingException mex) {



      mex.printStackTrace();

    }

 

%>



</body>

</html>

PopupAuthenticator类的代码如下：



package com.yang;



import javax.mail.*;

import java.util.*;



public class PopupAuthenticator extends Authenticator { 



	String username, password;



	public PopupAuthenticator(String username, String password) {

		this.username = username;

		this.password = password;

	}



	public PasswordAuthentication getPasswordAuthentication() { 



		return new PasswordAuthentication(username, password);  

		}

}

执行时报错：
com.sun.mail.smtp.SMTPSendFailedException: 503 Error: need EHLO and AUTH first !
我估计身份验证失败，但我已经将qq邮箱的smtp/pop开关打开了，我的用户名（就是qq号吧），密码应该没问题吧。问题在哪里呢？改用163邮箱时，又出了下面的问题：

实在不知道如何解决，只好问各位了。

另外，有没有不用smtp验证的服务器？
