C#

protected void btnsubmit_Click(object sender, EventArgs e)
    {
        Response.Write("you have applied" + ddl.SelectedItem.ToString());

        System.Net.Mail.MailMessage mm = new System.Net.Mail.MailMessage();
        mm.To.Add(new System.Net.Mail.MailAddress("iyalarasi.r@winxsolutions.com"));
        mm.From = new System.Net.Mail.MailAddress("iyalarasi.r@winxsolutions.com");
        mm.Sender = new System.Net.Mail.MailAddress("iyalarasi.r@winxsolutions.com");
        mm.Subject = "Request for Leave";
        mm.Body = txteno .Text+"request"+ddl.SelectedItem .ToString ()+"leave";
        mm.IsBodyHtml = true;
        mm.Priority = System.Net.Mail.MailPriority.High; // Set Priority to sending mail
        System.Net.Mail.SmtpClient smtCliend = new System.Net.Mail.SmtpClient();
        smtCliend.Host = "pop.1and1.com";
        smtCliend.Port = 25;    // smtp port no            
        smtCliend.Credentials = new NetworkCredential("User Name", "Password");
        smtCliend.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
        try
        {
            smtCliend.Send(mm);
        }
        catch (System.Net.Mail.SmtpException ex)
        {
            lblmsg.Text = ex.ToString();
        }
        catch (Exception exe)
        {
            lblmsg.Text = "\n\n\n" + exe.ToString();
        }
    }
