[postfix-es] Urgente - mail transport unavailable

[irodriguez]

Buenas Toni,

me temo que con esa información poco, si no nada, vamos a poder hacer. 
Aún así, revisa los logs de errores (mail.err por norma general) y 
haz un listado de la cola (mailq). Revisa también otros parámetros 
como ocupación de disco, swap usada, memoria libre, estado de los 
servicios que intervengan en tu sistema de correo (¿greylist? ¿amavis?). 
También puedes hacer pruebas de resolución del MX de los dominios 
que tengas en cola.

Un saludo

Iñaki R.
