javamail发送邮件成功 但是却接收不到邮件？
我用java写了一个发送邮件的程序，提示发送成功，但是发送到的邮箱却收到不邮件？这是为什么
package cn.itcast;

import java.util.Properties;

import javax.mail.Address;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class Demo1 {

/**
* @param args add by zxx ,Feb 5, 2009
*/
public static void main(String[] args) throws Exception{
// TODO Auto-generated method stub
Properties props = new Properties();
props.setProperty("mail.smtp.auth", "true");
props.setProperty("mail.transport.protocol", "smtp");
Session session = Session.getInstance(props);
session.setDebug(true);

Message msg = new MimeMessage(session);
msg.setText("nengshoudaoma");
msg.setFrom(new InternetAddress("haosiweishizhu@sohu.com"));

Transport transport = session.getTransport();
transport.connect("smtp.sina.cn", 25, "haosiweishizhu", "haosiwei");
transport.sendMessage(msg,new Address[]{new InternetAddress("wangzhiqing0327@sohu.com")});

//transport.send(msg,new Address[]{new InternetAddress("itcast_test@sohu.com")});
transport.close();
}

}

运行提示：
