[postfix-es] bloquear usuarios que no son del dominio que envian a mi dominio

[Rodrigo Cortes Cano]

Sorry por el html. Mala costumbre del outlook

bue, encontre la solucion a mi problema leyendo en parte la lista en
ingles


El problema es que estaba recibiendo correos de supuestos usuarios del
dominio que no existen.


como por ejemplo que me llego un correo de juan en dominio.com y ese
usuario no existe. El correo venia de afuera de la empresa. Entonces me
pregunte como poder evitar los recibos de este tipo de correos sin
alterar mi conf en la cual tengo permitidos usuarios auth y algunas ip.


mi postconf -n es

solucion reject dominio.com en el  client restriction
-->check_sender_access hash://etc/postfix/domain

saludos
