jmail发送总是被决绝

 Properties prop=new Properties();
        prop.setProperty("mail.smtp.auth", "true");
        prop.setProperty("mail.transport.protocol", "smtp");
Session session=Session.getInstance(prop);
session.setDebug(true);
  
          Message msg=new MimeMessage(session);
          msg.setText("hello jmail!");
          msg.setFrom(new InternetAddress("laiwei"));
          
  Transport trans=session.getTransport();
  trans.connect("smtp.sohu.com", 25, "aloyise", "135129");
  trans.sendMessage(msg, new Address[]{new InternetAddress("[email protected]")});
  trans.close();
账号是我现注册的，报的错是com.sun.mail.smtp.SMTPSendFailedException: 550 5.7.1 Command rejected
我查了下说是地址不正确才会报的错，但是我搞不明白，换了好几个地址都不行，请达人指教

  1.   


    javamail 用法有两种：1.不需要验证
     jsp版本<%@ page language="java" pageEncoding="UTF-8" contentType="text/html;charset=utf-8" %>
    <%@ page import=" javax.mail.*, javax.mail.internet.*, javax.activation.*,java.util.*" %>
    <html>
    <head>
    <TITLE>JavaMail 电子邮件发送系统</TITLE>
    </HEAD>
    <BODY><%
    try{    Properties props = new Properties();
        
        Session sendMailSession = Session.getInstance(props, null);
            Message newMessage = new MimeMessage(sendMailSession);    newMessage.setFrom(new InternetAddress("<[email protected]>"));
        newMessage.setRecipient(Message.RecipientType.TO, new InternetAddress("<[email protected]>"));
        newMessage.setSubject("subject21");
        newMessage.setSentDate(new Date());    newMessage.setText("text21");    Transport transport = sendMailSession.getTransport("smtp");
        transport.connect("smtp.163.com", "tj_yangyongfu", "11111111111111");
        newMessage.saveChanges();
        transport.sendMessage(newMessage, newMessage.getAllRecipients());
        transport.close();%><p>你的邮件已发送，请返回。</p><%    }
        catch(Exception e){    
            e.printStackTrace();
            out.println(e.toString());
        }%></BODY>
    </HTML>
    2.需要验证 此时又有两种写法
    2.1
    <%@ page language="java" pageEncoding="UTF-8" contentType="text/html;charset=utf-8" %>

        props.put("mail.smtp.auth","true");
        
        Session sendMailSession = Session.getInstance(props, null);
        Message newMessage = new MimeMessage(sendMailSession);
        newMessage.setFrom(new InternetAddress("[email protected]"));
        newMessage.setRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"));
        newMessage.setSubject("subject21");
        newMessage.setSentDate(new Date());
        newMessage.setText("text21");
        Transport transport = sendMailSession.getTransport("smtp");
        transport.connect("smtp.163.com", "[email protected]", "");
        newMessage.saveChanges();
        transport.sendMessage(newMessage, newMessage.getAllRecipients());
        transport.close();%>
    <p>你的邮件已发送，请返回。</p>
    <%
        }
        catch(Exception e){    
            e.printStackTrace();
            out.println(e.toString());
        }
