         // props.put("mail.smtp.user", "jb_china2004");
         //props.put("mail.smtp.password", "不能说");
把注释去掉,写一个授权类:
public class MyAuthenticator extends javax.mail.Authenticator
{
private String m_username = null;
private String m_userpass = null;public void setUsername(String username)
{
 m_username = username;
}public void setUserpass(String userpass)
{
 m_userpass = userpass;
}public MyAuthenticator (String username, String userpass)
{
   super();   setUsername(username);
   setUserpass(userpass);}
public PasswordAuthentication getPasswordAuthentication()
{  return new PasswordAuthentication(m_username,m_userpass);
}
}
//***********************
sendMailSession = Session.getInstance(props, new MyAuthenticator(username,password));

import javax.mail.Authenticator;

   private String m_username = null;
   private String m_userpass = null;
   public void setUsername(String username) 
   {
      m_username = username;
   }
   public void setUserpass(String userpass) 
   {
      m_userpass = userpass;
   }
   public MyAuthenticator (String username, String userpass) 
   {
      super();
      setUsername(username);
      setUserpass(userpass);
   }
   public PasswordAuthentication getPasswordAuthentication() 
   {
      return new PasswordAuthentication(m_username, m_userpass);
   }
}
import javax.mail.*;

import javax.mail.internet.*;public class SendMail 
{
   public static void main(String[] args) 
   {
      try 
      {
         Properties props = new Properties();
         Session sendMailSession;
         Store store;
         Transport transport;
         props.put("mail.smtp.host", "smtp.163.com");
         
         props.put("mail.smtp.user", "jb_china2004");
         props.put("mail.smtp.password", "jbChina2004");
         //props.put("mail.smtp.auth","true");
         //sendMailSession = Session.getInstance(props, null);
         sendMailSession = Session.getInstance(props, new MyAuthenticator("jb_china2004","jbChina2004"));
         Message newMessage = new MimeMessage(sendMailSession);
         newMessage.setFrom(new InternetAddress("[email protected]"));
         newMessage.setRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"));
         newMessage.setSubject("测试发信");
         newMessage.setSentDate(new Date());
         newMessage.setText("测试发信成功，欢喜之中");
         transport = sendMailSession.getTransport("smtp");
         transport.send(newMessage);
         System.out.println ("发送成功");
      }
      catch(Exception e) 
      {
         e.printStackTrace();
      }
   }
}还是不好用，
提示
javax.mail.MessagingException:553 you are not authorized to send mail as<mail from <[email protected]>>,authentication is required密码也告诉你啦， 麻烦你帮忙看一下呸，我没做过邮件发送， 都好几天没弄出来啦！
