为什么用JAVA发送邮件，只有标题，没有正文？（100分请教）
socket = new Socket(smtp.getText(), 25);
  in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
  out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())));
  send(null);
  send("HELO "+java.net.InetAddress.getLocalHost().getHostName());
  send("AUTH LOGIN");
  send(Base64.encode("n71929688"));
  send(Base64.encode("12071208"));
  send("MAIL From:"+from.getText());
  send("RCPT To:"+to.getText());
  send("DATA");
  String a = "\r\n.\r\n";
   
  out.println("Content-Type: text/plain;charset="+"GB2312");
  out.println("adslfjlasjdfalsdfj");

  out.flush();
  send(a);


 public void send(String msg) throws IOException
  {
  if(msg!=null)
  {
  out.println(msg);
  out.flush();
  }
   
   
  String line = in.readLine();
  if(line != null)
  state.setText(state.getText()+line+"\n");
  }

这是相关代码

呵呵！ 邮件协议规定，最前面的是header,里面是subject,datetime等内容，

然后以一个空行标志主体内容的开始

然后才是.结束，比如

subject:121212121212

body
.


你的那个只输出了header部分，你应该再看看协议
