Customer reported us e-mails when "from" and "to" are the same (it is customer's e-mail)
E-mail is not sent of course from our server.

To: [email protected]
From: [email protected]

In postfix it was a simple option (reject_unauth_destination), to prevent such fraud e-mail. But exim in cPanel receives such e-mails and customers are confused. How to prevent it ?
