I contacted webhostforlife and they suggested the following cange and it worked:

SmtpClient smtp = new SmtpClient("");

                //to authenticate we set the username and password properites on the SmtpClient
                smtp.Credentials = new NetworkCredential("", "password");


what do I need to change to so that  the contact page and other section pass the smtp script they suggest?
