You don't want to do this. Error messages come in with empty sender,
and rejecting errors causes work on innocent people's systems (double
bounces) and keeps your users from knowing that e-mail they sent
didn't reach the intended recipient.

It will also bring you quickly into a block list on rfc-ignorant.org

knowledge of their trade are allowed to run mail servers
