如何在J2ME程序中直接发送邮件

void sendMail() {
   SocketConnection sc = null;
   InputStream is = null;
   OutputStream os = null;

   //登录到邮件服务器
   try {
      byte b[] = new byte[200];
      int total = 0;
      sc = (SocketConnection)
         Connector.open("socket://" + servAdd + ":110");
      is = sc.openInputStream();
      os = sc.openOutputStream();
      os.write( ("USER  sender@domain.com ").getBytes());
      total = is.read(b);
      response += new String(b, 0, total);
      os.write( ("PASS?123\r\n").getBytes());
      total = is.read(b);
      response += new String(b, 0, total);
      //发送邮件
      sc = (SocketConnection) Connector.open("socket://" + serverAdd + ":25");
      is = sc.openInputStream();
      os = sc.openOutputStream();
      os.write( ("HELO there" + "\r\n").getBytes());
      os.write( ("MAIL FROM:  sender@domain.com ").getBytes());
      os.write( ("RCPT TO:  receiver@domain.com ").getBytes());
      os.write("DATA\r\n".getBytes());
      os.write( ("From:  sender@domain.com ").getBytes());
      os.write( ("To:  receiver@domain.com ").getBytes());
      os.write( ("Subject: " + subject + "\r\n").getBytes());
      os.write( (msg + "\r\n").getBytes()); // message body
      os.write(".\r\n".getBytes());
      os.write("QUIT\r\n".getBytes());
   }
   catch (Exception e) {}
}
