ASP.NET is not a mail server. Your users are sending email to a mail server, not to an ASP.NET application. If you want to send an email programmatically when a user fills out a form or clicks a link to your ASP.NET application, you can do this of course. Simply search for [search]ASP.NET email[/search] for plenty of examples.
If you want your mail server to send an auto-response, read the documentation for your mail server.
