I still need to append the user name to the domain name. This application is an internal app. In other words it is going to be used only by internal customers i.e. employess. So, instead of using Active Directory to get the user name. I found it eaiser to use Windows Authentication WA. So, the app is authenicating the user name from  single sign on and the removing the \\ before there user name. The next step is to take the user name that has already been authenticated using WA and that has had the \\ split away from the user name and appending that user name to the company's domain name i.e. company.net to the from field in the email button click event. I know that the email code is functional when I put only my company email address into the from field.
Code:
 protected void btnSend_Click(object sender, EventArgs e)
        {
            string email = String.Empty;
            string username = HttpContext.Current.User.Identity.Name.Split('\\')[1];
            MailMessage mail = new MailMessage();

            try
            {


                mail.From = new MailAddress(username +company@domain.net);
                mail.To.Add("company@domain.net");                      // put To: address here
                mail.Subject = "IT Account Request Form";            // put subject here      
                mail.Body = TextBox9.Text;                          // put body of email here

                // put smtp server you will use here
                SmtpClient smtp = new SmtpClient();
                smtp.Host = "ip address of email server";
                smtp.Port = 25;
                smtp.Send(mail);

                Label1.Text = "Your message was successfully sent.";
            }
            catch (Exception ex)
            {
                Label1.Text = "An error occurred sending your e-mail, the error is:\r\n" + ex.Message;
            }
        }
