用socket连接163发邮件服务器：

var ba:ByteArray = new ByteArray();

ba.writeUTFBytes("MAIL FROM: <fanxing518@163.com>\r\n");
ba.writeUTFBytes("RCPT TO: <fanxingzjy@gmail.com>\r\n");
ba.writeUTFBytes("data\r\n");
ba.writeUTFBytes("From: fanxing518@163.com\r\n");
ba.writeUTFBytes("To: fanxingzjy@gmail.com\r\n");

ba.writeUTFBytes("Subject: testSubject\r\n");
ba.writeUTFBytes("Mime-Version:1.0\r\n");
ba.writeUTFBytes("Content-Type:text/plain\r\n");
ba.writeUTFBytes("\r\n");
ba.writeUTFBytes("HELLO\r\n");
ba.writeUTFBytes(".\r\n");

socket.writeBytes(ba);
socket.flush();
