Every MTA already does this, *if* you mean reject the mail:
telnet smtp.utdallas.edu 25
Connected to smtp.utdallas.edu.
Escape character is '^]'.
220 smtp1.utdallas.edu ESMTP Postfix
MAIL FROM: testing at stovebolt.com
RCPT TO: bogus at utdallas.edu
554 <bogus at utdallas.edu>: Recipient address rejected: Access denied
Connection closed by foreign host.
If you mean, send an autoreply to the sender, as others have pointed out,
you do *NOT* want to do that. If you do, your server will get blacklisted
