Evitar relay interno en postfix

[Maykel Franco Hernández]

Hola muy buenas, he montado un servidor de correo con el fantastico
panel de control ISPCONFIG en ubuntu y el caso es que creo que estan
enviado correos a una misma cuenta de anuncios y propaganda y utilizan
como remitente la misma direccion de correo que la cuenta destino, dejo
una captura, como podría evitar esto??
