<script type="text/javascript" ></script> 
        <script language="javascript">
            $(document).ready(function() {
 
                $("#btnClick").click(function() {
                    var email = $("#txtemail").val();
                    $.ajax({
                        type: "POST",
                        url: "TestingEmail.aspx/DNSValidation",
                        data: "{EmailAddress:" + email.toString() + "}",
 
                        success: function(response) {
                        alert(response.d);
//                            if (response.bolDNSFlag != "true") {
//                                alert("Plz try again");
//                                $("#txtemail").focus();
//                            }
                        },
                        error: function() {
                            alert("Error");
                        }
                    });
                    //Call the PageMethods
                    $.ajax(options);
 
                });
 
 
            });
        </script>
<script type="text/javascript" ></script> 
        <script language="javascript">
            $(document).ready(function() {

                $("#btnClick").click(function() {
                    var email = $("#txtemail").val();
                    $.ajax({
                        type: "POST",
                        url: "TestingEmail.aspx/DNSValidation",
                        data: "{EmailAddress:" + email.toString() + "}",

                        success: function(response) {
                        alert(response.d);
//                            if (response.bolDNSFlag != "true") {
//                                alert("Plz try again");
//                                $("#txtemail").focus();
//                            }
                        },
                        error: function() {
                            alert("Error");
                        }
                    });
                    //Call the PageMethods
                    $.ajax(options);

                });


            });
        </script>

and server side is

JavaScript / DHTML / AJAX Syntax (Toggle Plain Text)
[WebMethod]
    public static string DNSValidation(string EmailAddress)
    {
        Boolean bolDNSFlag = false;
        try
        {
            if (isEmail(EmailAddress.Trim()))
            {
                string[] host = (EmailAddress.Trim().Split('@'));
                string hostname = host[1];
 
                IPHostEntry IPhst = Dns.GetHostEntry(hostname);
                IPEndPoint endPt = new IPEndPoint(IPhst.AddressList[0], 25);
                Socket s = new Socket(endPt.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
                s.Connect(endPt);
                bolDNSFlag = true;
            }
        }
        catch (Exception exp)
        {
            bolDNSFlag = false;
        }
        return bolDNSFlag.ToString();
    }
[WebMethod]
    public static string DNSValidation(string EmailAddress)
    {
        Boolean bolDNSFlag = false;
        try
        {
            if (isEmail(EmailAddress.Trim()))
            {
                string[] host = (EmailAddress.Trim().Split('@'));
                string hostname = host[1];

                IPHostEntry IPhst = Dns.GetHostEntry(hostname);
                IPEndPoint endPt = new IPEndPoint(IPhst.AddressList[0], 25);
                Socket s = new Socket(endPt.AddressFamily, SocketType.Stream, ProtocolType.Tcp);
                s.Connect(endPt);
                bolDNSFlag = true;
            }
        }
        catch (Exception exp)
        {
            bolDNSFlag = false;
        }

Re: how to call server side method from jquery

Fist (in FireFox) press CTRL + SHIFT + J and load the Error console. Clear the contents before you reload the page. When you reload the page, if errors appear, fix them.

Is the call jquery ajax call being made? If you're using firefox, install the firebug extension. This extension will allow you to look at the ajax calls that are being made. It will make it easier for you to debug.

Also, jQuery offers a much simpler construct for ajax.

JavaScript / DHTML / AJAX Syntax (Toggle Plain Text)
jQuery.post( 
	"TestingEmail.aspx/DNSValidation", 
	{"EmailAddress": email.toString()},
	function(data){
		alert(data);
	});
jQuery.post( 
	"TestingEmail.aspx/DNSValidation", 
	{"EmailAddress": email.toString()},
	function(data){
		alert(data);
	});

Also, I think you may be quoting the wrong parts in the data variable. Not sure on that, the error console will help you out there.

Re: how to call server side method from jquery

Change line 10 to:

JavaScript / DHTML / AJAX Syntax (Toggle Plain Text)
data: "{EmailAddress: " + "'" + email + "'" +  " }",
 
/* Weird JavaScript :)
 
BTW: All of these shall work:
 
 data: '{"testData":"testing"}',
 data: "{testData: " + $('#<%= ddlCtrl.ClientID %>').val() + " }",
 data: "{testData: " + "'" + inputData.val() + "'" + " }",
 
~ Boris Momtchev
*/
data: "{EmailAddress: " + "'" + email + "'" +  " }",

/* Weird JavaScript :)

BTW: All of these shall work:

 data: '{"testData":"testing"}',
 data: "{testData: " + $('#<%= ddlCtrl.ClientID %>').val() + " }",
 data: "{testData: " + "'" + inputData.val() + "'" + " }",
