哪位哥哥懂win7的smtp配置啊。java发送email老是报错。

看了好多smtp的配置，基本都是xp，win7的有，照上面配置也不管用啊。
下面是我的java代码：

package public_use;



import java.util.Properties;



import javax.mail.*;

import javax.mail.internet.*;



public class SendEmail {



	public void initAll(){

		Properties pro = System.getProperties();

		pro.put("mail.host", server);

	//	pro.put("mail.smtp.port", port);

	//	pro.put("mail.smtp.auth", "true");

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

		

		Session session = Session.getDefaultInstance(pro,null);

		session.setDebug(true);

		Transport trans = null;

		try {

			trans = session.getTransport("smtp");

			trans.connect(server, "binge", "6");		

		} catch (Exception e) {

			System.out.println("111111===");

			e.printStackTrace();

		}

		

		

		MimeMessage mes = new MimeMessage(session);

		try {

			mes.setFrom(new InternetAddress(server));

			InternetAddress[] toAddress = new InternetAddress[1];

			toAddress[0] = new InternetAddress(receiver);

			mes.setRecipients(Message.RecipientType.TO, receiver);

			mes.setSubject("java邮件测试");

			mes.setText("这是内容啊 啊啊啊 啊啊", "gbk");

			mes.saveChanges();

			trans.sendMessage(mes, toAddress);

			System.out.println("发送成功。。。");

		} catch (Exception e) {

			System.out.println("222222===");

			e.printStackTrace();

		}

	}

	public static void main(String[] args){

		new SendEmail();

	}

	public SendEmail(){

		System.out.println("正在启动发送邮件。。");

		initAll();

	} 

	private String receiver = "943366739@qq.com";

	private String server = "127.0.0.1";//邮件服务器



}

下面是报错：
正在启动发送邮件。。

防火墙关了也不管用。还有，smtp里把端口改成24，这报错的端口还是25，而且停用服务是报同样的错。好像我的smtp跟没开启服务似的。
求高手大哥给解~~
