[Postfix-es] Postfix no envia mails

Lun Sep 5 09:15:47 CEST 2005


Hola a todos:

Tengo configurado un sistema de correo con Postfix, Cyrus IMAP, Cyrus SASL, 
clamAV, SpamAssassin y Amavis; sobre un Debian.

Despues de largas peleas con los diferentes archivos de configuración, 
permisos y el Postfix; esta funcionando todo el sistema correctamente, 
exceptuando una pequeña cosa: el envio de emails desde mi dominio a dominios 
externos.

En el mail.log nos podemos encontrar esto cuando intentamos enviar un correo 
a un dominio exterior:
