Hi, You should think about situation when local user made mistake and write wrong local address. Then your rule will drop this user to send mail inside your domain. Because i'm a noob, it was easy for me to set fail2ban.

Is it possible, to configure exim, so it will drop/reject message processing after first "Unknown user" ?
