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:

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

Recommended:

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.
