如何在J2ME程序中直接发送邮件

下边的代码说明了如何在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){}

  }
