SMTP 邮件服务器身份验证怎么搞？？？

Question

用base64，找java源码和我联系[email protected]

Answer 1

Properties prop = new Properties();
prop.setProperty("mail.transport.protocol","smtp");
prop.setProperty("mail.smtp.host","smtp.sina.com.cn");//Sina的好像是这个地址吧
prop.setProperty("mail.smtp.auth","true");Session session = Session.getInstance(prop,
            new Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication("YourUserNameInSina","YourPassword");
                }
            });
 Transport trans = session.getTransport();
//sendmessage，使用trans来传送，不要用静态方法
trans.close();如果是其他smtp服务器你换一下上面得代码就行了

Answer 3

to ChDw(米) Session  Transport这两个类是不是要到sun上面新下载啊？

Answer 4

if(authorization==true){
            if(!sendToServer("AUTH LOGIN"))
              return;
            if(!responseFromServer("334",
                                   "未知错误,也许你的服务器不需要身份验证!"))
              return;
            user=new BASE64Encoder().encode(user.getBytes());
            if(!sendToServer(user))
              return;
            if(!responseFromServer("334",
                                   "注册失败,无效的用户名!"))
              return;
            password=new BASE64Encoder().encode(password.getBytes());
            if(!sendToServer(password))
              return;
            if(!responseFromServer("235",
                                   "注册失败,请检查你的用户名和密码!"))
              return;
          }
我自己做的smtp客户端的一部分代码

//协议对话部分
try{
          clientSocket=new Socket(host,port);          outToServer=
              new DataOutputStream(
                 clientSocket.getOutputStream());
          inData=
              new BufferedReader(
                 new InputStreamReader(clientSocket.getInputStream()));          if(!responseFromServer("220","无法解析主机"))
            return;
          if(!sendToServer("EHLO stmp.taohoo.com"))
            return;
          if(!responseFromServer("250","未知错误,请查看LOG!"))
            return;
          if(authorization==true){
            if(!sendToServer("AUTH LOGIN"))
              return;
            if(!responseFromServer("334",
                                   "未知错误,也许你的服务器不需要身份验证!"))
              return;
            user=new BASE64Encoder().encode(user.getBytes());
            if(!sendToServer(user))
              return;
            if(!responseFromServer("334",
                                   "注册失败,无效的用户名!"))
              return;
            password=new BASE64Encoder().encode(password.getBytes());
            if(!sendToServer(password))
              return;
            if(!responseFromServer("235",
                                   "注册失败,请检查你的用户名和密码!"))
              return;
          }
          if(!sendToServer("MAIL FROM:<"+mailfrom+">"))
            return;
          if(!responseFromServer("250","错误！可能你还没有注册，或者输入的发件人地址不正确"))
            return;
          if(!sendToServer("RCPT TO:<"+mailto+">"))
            return;
          if(!responseFromServer("25","错误！无效的发件人地址"))//回复应该是250或者251
            return;
          if(!sendToServer("DATA"))
            return;
          if(!responseFromServer("354","未知错误,请查看LOG!"))
            return;
          if(!sendToServer("To:"+mailto))
               return;
          if(!sendToServer("From:"+mailfrom))
               return;
          if(!sendToServer("Subject:"+subject))
               return;
           if(!sendToServer(content))
             return;
           String msgEnd=new String(String.valueOf("."));
           if(!sendToServer(msgEnd))
             return;
           if(!responseFromServer("250","未知错误!"))
            return;
          if(!sendToServer("QUIT"))
            return;
          if(!responseFromServer("221","未知错误!"))
            return;
          inData.close();
          outToServer.close();
          clientSocket.close();
          JOptionPane.showMessageDialog(messageFrame,"邮件已成功发出!");
        }
        catch (UnknownHostException ex){
           JOptionPane.showMessageDialog(
                    messageFrame,ex.toString(),"Error",
                       JOptionPane.ERROR_MESSAGE);
        }
        catch (IOException ee){
          JOptionPane.showMessageDialog(
              messageFrame,ee.toString(),"Error",
                 JOptionPane.ERROR_MESSAGE);
        }
        finally{
          try{
            clientSocket.close();
            messageFrame.addMessageToMessageFrame("连接断开");
          }
          catch(IOException ioe){
            JOptionPane.showMessageDialog(
              messageFrame,ioe.toString(),"Error",
                 JOptionPane.ERROR_MESSAGE);
            messageFrame.addMessageToMessageFrame("连接断开");
          }
        }这是协议对话部分
//服务器的反应,
    boolean responseFromServer(String cmd,String errorMessage){
      String responseSentence;
      try {
        responseSentence = new String(inData.readLine());
        if (!responseSentence.startsWith(cmd)) {
          return false;
        }
      }
      catch (IOException ioex) {
        return false;
      }    while(responseSentence.startsWith("-",3)){
            try{
              responseSentence = new String(inData.readLine());            }
            catch(IOException ioeX){
                   return false;
            }          }
          return true;
    }//向服务器发送一个命令
  boolean sendToServer(String msg){
   try{
     outToServer.writeBytes(msg+'\r'+'\n');
   }
   catch(IOException ioex){
      return false;
   }
   return true;
  }}
