No sóc un spammer !

Posted in inet at 7:17 pm by brainstorm

Tal com comentava fa un mes, estic en el procés de de-llistarme de les principals llistes d’spam. Doncs bé, primer vaig demanar per segon cop a auna que em canviessin el registre PTR ja que el primer cop, només van fer el canvi en un dels seus servidors… abans del canvi definitiu els servidors responien així:

$ host 62.57.0.38 mayor.auna.net
38.0.57.62.in-addr.arpa domain name pointer 38.red-62-57-0.user.auna.net.

$ host 62.57.0.38 ramblas.auna.net
38.0.57.62.in-addr.arpa domain name pointer nopcode.org.

Ara ja està corregit, és a dir, els dos resolen a nopcode.org. Després vaig omplir el form de de-listing de SORBS-DHUL explicant la situació:

I’ve recently switched to static IP address within my ISP’s IP Space, I pay 1€/month for my IP to be static. I’ve followed all the requisites you demand to de-list my server, for instance:

$ host 62.57.0.38
38.0.57.62.in-addr.arpa domain name pointer nopcode.org.

As you see, my PTR register points back to my domain (I’ve also requested that change in my ISP). Before, it was pointing to a generic dynamic pool. I’ve also corrected TTL times as you demand, please, if it’s something left to fix, notify me.

Thank you.

I en dos dies em van de-llistar :-) :

Netblock: 62.57.0.0/18(62.57.0.0-62.57.63.255)
Record Created: Mon Nov 24 12:58:03 2003 GMT
Record Updated: Mon Nov 24 12:58:03 2003 GMT
Additional Information: [TTL 86400] nopcode.org. [62.57.0.38] excluded
Listed as an exception and therefore NOT blocked.

S’han de seguir alguns passos (senzills) per a conseguir que t’eliminin de la llista negra, en concret, aquests són els checks que fa SORBS:

  1. MX records are looked up for the domain entered.
  2. MX records with short TTLs are discarded.
  3. A records are looked up for each MX record with acceptable TTLs (ttl>43200).
  4. A records with short TTLs are discarded.
  5. The IP addresses in each A record are resolved to PTR records.
  6. IP addresses with PTR records that have short TTLs are discarded.
  7. IP addresses with PTR records without matching A records (in previous lookups) are discarded.

    8. Any remaining IP addresses are added to the DUHL exclusions database.

Ah, se’m oblidava, requisits previs imprescindibles (en el cas d’auna):

  1. Demanar IP fixa. No té cap sentit demanar que t’arreglin els PTR’s si la IP va variant (trucar al 900 855 555). Cobren 1€ al mes per aquest canvi.
  2. Demanar que canviin els registres PTR pq apuntin al teu domini (enviar mail a dominios.tecnico_nospam_At_auna.es)

Aviam si hi ha sort amb NJABLDYNA i amb FIVETENSRC :-).

EDIT: Doncs he tingut sort ! He estat esborrat de les dues llistes que em faltaven al cap de 2 dies d’enviar el mateix mail que vaig enviar a SORBS :-)
