Resolved Spamassassin RDNS_NONE false positive plesk onyx

Hi Marlon,

at the moment, your domain

micallejero.es resolves to 85.214.143.130

but

85.214.143.130 resolves to nodos.net


Pls. include your current "hostname" of your server in your SPF - entry at the correct position ( the "~/-/?all" option is the LAST and therefore the ending, when requests are done ) :

Current:
Code:
v=spf1 +a +mx -all +a:nodos.net

Recommended:
Code:
v=spf1 +mx +a +a:nodos.net ip4:85.214.143.130 ?all

For more informations to the documented standarts, pls. read: => RFC 7208 - Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1
 
Hi Marlon,

sorry, but you should CHECK and CORRECT your settings ( and pls. keep in mind, that DNS - changes CAN take up to 48 hours, untill all worldwide nameservers are synced! ).

Some additional investigations:

You setup the "myhostname" to "vps.nodos.net" in your postfix - configuration ( /etc/postfix/main.cf ), but

The reverse entry for "85.214.143.130" is "nodos.net"

Your mail - server answers with "srv-nodos.com.es" ( which is now matching the entry at "/etc/hostname" ), but this doesn't change the rDNS - setup for your IP "85.214.143.130".

You now changed the SPF - entry to "v=spf1 +mx +a +a:srv-nodos.com.es ip4:85.214.143.130 ?all" , but again, this doesn't match your rDNS - entry for your IP.​

Pls. check as well your file "/etc/hosts" and make sure, that your settings are correct. ;)
