Not able to send the Toast Push notification in wp7 - windows-phone-7

Question

I always get the 404 error.Below is my complete code for sending the push notification of type Toast from the wcf service.Anything wrong with the message ?
string channelURI = "http://db3.notify.live.net/throttledthirdparty/01.00/AgAAAAQUZm52OjBEMTRBNDEzQjc4RUFBRTY";
HttpWebRequest sendNotificationRequest = (HttpWebRequest)WebRequest.Create(channelURI);
//Indicate that you'll send toast notifications!
sendNotificationRequest.ContentType = "text/xml";
sendNotificationRequest.Headers.Add("X-WindowsPhone-Target", "toast");
sendNotificationRequest.Headers.Add("X-NotificationClass", "2");
sendNotificationRequest.Method = "POST";
sendNotificationRequest.Headers.Add("X-MessageID",Guid.NewGuid().ToString());
if (string.IsNullOrEmpty(message)) return "empty cannot be sent";
//send it
var msg = string.Format("sample toast message", "Toast Message", "This is from server");
byte[] notificationMessage = Encoding.UTF8.GetBytes(msg);
sendNotificationRequest.ContentLength = notificationMessage.Length;
//Push data to stream
using (Stream requestStream = sendNotificationRequest.GetRequestStream())
{
requestStream.Write(notificationMessage, 0, notificationMessage.Length);
}
//Get reponse for message sending
HttpWebResponse response = (HttpWebResponse)sendNotificationRequest.GetResponse();
string notificationStatus = response.Headers["X-NotificationStatus"];
string notificationChannelStatus = response.Headers["X-SubscriptionStatus"];
string deviceConnectionStatus = response.Headers["X-DeviceConnectionStatus"];
return notificationStatus;
