[postfix-es] error: Delayed Mail (still being retried)

[antonio]

Hola a todos.

Estos dos días mi postfix no está enviando los correos. Me los devuelve 
todos poniendo como asunto "Delayed Mail (still being retried)" y en el 
cuerpo del mensaje:

This is the Postfix program at host servidor.cprlogrono.org.

Esta claro que lo que me dice postfix es que ha intentado durante 4 
horas enviar el mensaje y al no poder me los devuelve.

Lo raro es que me sucede con todos los mensajes y no se que tengo que 
hacer para que me vuelva a funcionar correctamente.

Saludos y gracias de antemano.
