Mi sistema de correo está loco!!

Gracias Dgranda.

Es normal, tengo 14 dominios bajo la misma IP y sólo puedo configurar la inversa para uno. Sin embargo si el resto de servicios es correcto, el email pasa totalmente por bueno, como así está sucediendo a rachas.

De todos modos ya he probado a cambiar la inversa al dominio con el que estoy haciendo las pruebas, y todo igual.

Un saludote!!

Antes de hacer millones de pruebas, asegúrate de:

- Configuraciones están aplicadas reiniciando los servicios correspondientes.
- Los servicios escuchan en la interfaz adecuada (ojo con mezclar IPv4 e IPv6).

Echando un vistazo rápido, parece que el registro inverso no está correcto:

$ dig onuboda.es | grep onuboda
; <<>> DiG 9.10.3-P4-RedHat-9.10.3-12.P4.fc23 <<>> onuboda.es
;onuboda.es. IN A
onuboda.es. 21599 IN A 37.187.5.234
$ dig -x 37.187.5.234 | grep PTR
;234.5.187.37.in-addr.arpa. IN PTR
234.5.187.37.in-addr.arpa. 21599 IN PTR onuba.com.
Suerte

Hola amigos:

Llevo todo el día liado con esto y no soy capaz de dar con la solución

Tengo todo lo que hay que tener para un servidor de correo seguro. Uso Plesk 11.5 sobre Centos 6.7, y mucha consola (por supuesto), por lo que tengo perfectamente SPF, DKIM, DomainKeys y Dmarc..., toda la carne en el asador vaya.

Os cuento la gran locura:

Cada vez que mando un email (estoy usando siempre el mismo dominio para hacer las pruebas) el servidor me hace una cosa distinta, porque a veces Gmail rechaza los correos, mientras que en Hotmail llegan a spam, y en múltiples ocasiones llegan perfectamente a Gmail y a Hotmail, correctamente a la bandeja de entrada. Luego vuelvo a probar y vuelve a rechazar uno y el otro a spam, y así sucesivamente, sin tocar nada!.

El 90% de las veces la herramienta Authentication Report me responde esto:
SPF check: pass
DomainKeys check: pass
DKIM check: pass
Sender-ID check: pass
SpamAssassin check: ham

Pero el 10% de las veces me responde esto:
SPF check: pass
DomainKeys check: pass
DKIM check: neutral
Sender-ID check: pass
SpamAssassin check: ham

Sin embargo, Mail Tester me da un 10/10 !!!, todo perfectísimo!!.

Quiero pensar que Dkim en ocasiones no firma, pero no logro averiguarlo, y en tal caso..., ¿por qué firma algunas veces sí y otras no?..., es muy raro!.

A continuación os pongo 4 trozos del maillog encabezados por una descripción mia:

Y así sucesivamente voy probando de vez en cuando, y cuando le da la gana llega, y cuando no, gmail lo rechaza y hotmail lo lleva a la bandeja spam.

El error que me tira gmail cuando lo rechaza es este:

gmail-smtp-in.l.google.com[2a00:1450:400c:c09::1b] said: 550-5.7.1
[2001:41d0:a:5ea::1] The IP address sending this message does not have
550-5.7.1 a PTR record setup. As a policy, Gmail does not accept messages
from 550-5.7.1 IPs with missing PTR records. Please visit 550-5.7.1
https://support.google.com/mail/answ...authentication for more 550
5.7.1 information. k74si739962wmc.97 - gsmtp (in reply to end of DATA
command)


Sin embargo cuando llega bien, miro el fuente del correo y me lo da todo como "pass".

Por favor, ¿alguna explicación?..., yo ya la hora que es estoy ciego. He regenerado las firmas dominio por dominio, he revisado configuraciones siguiendo extrictamente todos los manuales, incluso he cambiado mas de 10 veces la ip inversa, y nada de eso es, porque siempre me hace lo mismo.

Gracias!!.


Edito: Acabo de hacer otra prueba desde el navegador (webmail), he enviado un email a 3 correos (gmail, hotmail y autocheck). Acaba de llegar a ambas cuentas perfectamente a la bandeja de entrada, y autocheck me responde con Pass a todo. Esto es increíble..., cuando le da el punto se pega media hora enviando a spam y gmail rechazando correos...
