Problema por Postfix en Centos 6.7

He tenido algunos problemas con el correo que se envía al dominio local rebota y cuando veo la cola de correo, su “aparecer dos errores –
1. Los correos electrónicos que se envían a la “root” – vienen con el mensaje = “user unknown”
2. Los correos electrónicos que se envían a user@domain.com de user2@domain.com – donde domain.com (es el dominio local configurada en el servidor) están subiendo con un message = “mail system configuration error” monitoreando el archivo “maillog”

(mail system configuration error)

X-Postfix; mail system configuration error

y el rebote del correo es el siguiente:
