sending mail using asp.net

i am trying to send mails using c# in asp.net page on a free asp server. i have wrote this code 

public string send_email()
{
    SmtpClient client = new SmtpClient("relay-hosting.secureserver.net", 25);
    string to = "[email protected]";
    client.DeliveryMethod = SmtpDeliveryMethod.Network;
    client.Credentials = new System.Net.NetworkCredential("[email protected]", "XXXXXXX");

    MailAddress fromAddress = new MailAddress("[email protected]", "Mona ");
    MailMessage message = new MailMessage();
    message.From = fromAddress;
    message.To.Add(to);
    message.Body = "This is Test message";
    message.Subject = "hi";

    client.Send(message); 
    message.Dispose(); 
    return "Email Send";
}

and wrote this in web.config

<mailSettings>
  <smtp from="[email protected]">
        <network host="relay-hosting.secureserver.net" port="25" userName="[email protected]" password="XXXXX"/>
  </smtp>

1) If you use web.config <mailsettings> configuration (and this is right!) you should not set SmtpClient programmatically, or configuration will be useless! 

 SmtpClient client = new SmtpClient();  
 MailMessage message = new MailMessage();  
 message.To.Add(to);  
 message.Body = "This is Test message";  
 message.Subject = "hi";`

this is enough, no server o from in code.

2) As Max's saying, this is not a code problem: this is a configuration problem! Try a server-port-user-password configuration using your mail client (outlook, thunderbird or any other) and if this works you just have to copy it in tag.

Make it so that you can allow anonymous emailing from your server where the page resides then you can set:

    client.UseDefaultCredentials = false;

and 

    message.From = "[email protected]";

and like Max Al Farakh said, use the provided SMTP server which you have rights to.

It's a security error from your SMTP server, not your code's fault. Probably because you use your Gmail credentials to access a non-gmail SMTP server.
