Hola a todos. He creado varias cuentas en mi nueva del WHM y recien los estoy empezando a usar. Ahora solo tengo un problema con los mails de los usuarios que tengo alojados en mi host. Varios de los correos que envian a hotmail, Berklee.net, etc no llegan o rebotan con el siguiente mensaje:
---------------------------------------------------------------------
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
[email protected]
SMTP error from remote mail server after MAIL FROM:<
[email protected]>
SIZE=2101:
host mx1.hotmail.com [65.54.244.136]: 550 Command rejected for policy reasons.
--------------------------------------------------------------------------
Ahora luego de revisar el estado del host haciendo uso del DNSREPORT.COM me sale este error, poniendo uno de los dominios con problemas: "clandestino.us"
--------------------------------------------------------------------------
ERROR: One or more of your nameservers reports that it is an open DNS server. This usually means that anyone in the world can query it for domains it is not authoritative for (it is possible that the DNS server advertises that it does recursive lookups when it does not, but that shouldn't happen). This can cause an excessive load on your DNS server. Also, it is strongly discouraged to have a DNS server be both authoritative for your domain and be recursive (even if it is not open), due to the potential for cache poisoning (with no recursion, there is no cache, and it is impossible to poison it). Also, the bad guys could use your DNS server as part of an attack, by forging their IP address. Problem record(s) are:
Server 69.16.243.46 reports that it will do recursive lookups. [test]
Server 69.16.243.45 reports that it will do recursive lookups. [test]
----------------------------------------------------------------------
Ahora estoy pensando que tiene que ver con las dns, supongo que tengo que configurar algo mas en el WHM, pero no se que. No se si tengo que crear private label nameservers.
Por favor si alguien sabe del tema o ha tenido experiencia con este problema por favor sus comentarios.
Gracias
Javier Silva
