		myDNSServers = myDNSClient.GetSystemDNSServers();
		myDNSClient.SetServers(myDNSServers);
		Console.WriteLine("Performing MX Lookup");
		MailExchangeData MXData;
		ArrayList myMXList;
		try
		{			
			myMXList = myDNSClient.MailExchangeLookup("www.SeekfordSolutions.com");
			Console.WriteLine("MX Lookup results:\r\nServer\tPreference\r\n");
			for(int iX=0; iX < myMXList.Count;iX++)
			{
				MXData = (MailExchangeData)myMXList[iX];
				Console.WriteLine(MXData.Server.ToString() + "\t" + MXData.Priority.ToString() + "\r\n");
