Hi friends,

The following is my code for sending mail with html body. it is working in the localhost. but when i uploaded to my windows server, it does not send email. without html file, i can send a mail from my server. I uploaded aspx file and html file and webconfig file in the same directory.

private string PopulateBody(string userName, string phone, string email, string message)
    {
        string body = string.Empty;
        using (System.IO.StreamReader reader = new System.IO.StreamReader(Server.MapPath("~/bodyPage.htm")))
        {
            body = reader.ReadToEnd();
        }
        body = body.Replace("{Name}", userName);
        body = body.Replace("{Phoneno}", phone);
        body = body.Replace("{Email}", email);
        body = body.Replace("{Message}", message);
        return body;
    }
    protected void btnSubmit_Click(object sender, EventArgs e)
    {
        try
        {
            MailMessage Msg = new MailMessage();
            // Sender e-mail address.
            Msg.From = new MailAddress(txtEmail.Text);
            // Recipient e-mail address.
            Msg.To.Add("info@dhuvara.com");
            Msg.Subject = txtEmail.Text;
            string message = PopulateBody(txtName.Text,txtphone.Text,txtEmail.Text,txtMessage.Text);
            Msg.Body = message;
            Msg.CC.Add("baskey2@gmail.com");
            Msg.IsBodyHtml = true;
            // your remote SMTP server IP.
            SmtpClient smtp = new SmtpClient();
            smtp.Host = "smtp.live.com"; 
            smtp.Port = 587;
            Msg.Priority = MailPriority.Normal;
            smtp.UseDefaultCredentials = false;
            smtp.Credentials = new System.Net.NetworkCredential("info@dhuvara.com", "SolaiMail");
            smtp.EnableSsl = true;
            smtp.Send(Msg);
            //Msg = null;
             lbltxt.Text = "Thanks for Contact us";
            // Clear the textbox valuess
            txtName.Text = "";
          //  txtSubject.Text = "";
            txtMessage.Text = "";
            txtEmail.Text = "";
        }
        catch (Exception ex)
        {
            Console.WriteLine("{0} Exception caught.", ex.ToString());
        }
