Your question is not clear enough; please elaborate the problems that you're facing in your application and ( if any ) the errors that are shown to you. SMTP functionality is enabled in IIS by default  you do not need to perform anything to enable and use it in your applications; web-based. All you need is the credentials for your SMTP server; such as Gmail Outlook etc. and some other details such as user/password port number to connect through etc. Then you can use the SMTP server functionality in your application too.
