Mention the domain which you use to validate in web.config file in this way In .cs file validate it in this way Configuration webConfig = WebConfigurationManager.OpenWebConfiguration(/Asp.net.Web);// here asp.net.web is ur project name string[] domainList = ConfigurationManager.AppSettings[DomainList].Split(';'); and validate the user in this way domainList.Contains(mailaddress.Host) // here the mail address is the address you enter
