                mail.From = new MailAddress("removed", "Interview study material");
                mail.To.Add(mailTo);
                mail.Subject = subject;
                mail.Body = "Please find attachment document!";

                var attachFile = new Attachment(FileUpload1.PostedFile.InputStream, strFileName);
                mail.Attachments.Add(attachFile);

                smtpServer.EnableSsl = true;
                smtpServer.Send(mail);

            }
            catch(Exception ex)
            {
