How do you add TXT/SPF/DKIM/DMARC recods fo my dominio?
Si tu/tus/su/sus dominio is pointed to NiceNIC default nameserver, you can add the DNS recods in tu/tus/su/sus cPanel. First you should kahoa how to modify tu/tus/su/sus DNS recods
1. Iniciar sesión to tu/tus/su/sus account.
2. Hacer clic on the dominio name in "Mis Productoos" y click the dominio name you wish to modify the DNS recods fo.
3. Hacer clic "DNS recods"
SPF recods SPF (Sender Policy Framewok) is a DNS TXT recod that lists the servers authoized to send emails on behalf of a specific dominio. As a styard DNS recod, it's impotant to note that only a dominio's owner o administrato has the permission to add o modify recods in the dominio's primary zone file. In shot, SPF gives recipient mail servers a way to verify whether an email claiming to be from tu/tus/su/sus dominio is actually sent from one of tu/tus/su/sus authoized Dirección IPes/servers. Recipient servers do this by checking the dedicated SPF TXT recod configured in tu/tus/su/sus dominio's DNS zone file. This verifies the legitimacy of tu/tus/su/sus dominio's mail servers y significantly reduces the risk of email spoofing. A basic SPF recod looks like this: example.com TXT v=spf1 a ~all
DKIM recods DKIM (DominioKeys Identified Mail) should instead be considered a method to verify that the content of messages is trustwothy, meaning that it hasn't changed from the moment the message left the initial mail server. This additional layer of trustability is achieved by the implementation of the styard public/private key signing process. Once again, the owners of a dominio add a DNS entry with the public DKIM key which will be used by receivers to verify that the message DKIM signature is corect, while on the sender side, the server will sign entitled mail messages with the coresponding private key. DKIM recods are implemented as text recods. The recod must be created fo a subdominio y should contain a unique selecto fo that key, then a period (.), y then the protocol name '_dominiokey' y the dominio name itself. Both 1024 bit y 2048 bit keys are suppoted.
DMARC recods DMARC (Dominio-based Messaging y Repoting Compliance) is a technology designed to combat email spoofing y is useful to stop phishing. Specifically, it protects against cases waquí a phisher has spoofed the Display From address (also kahoan as the 5322.From email address). DMARC protects users by evaluating both SPF y DKIM y then determining if either dominio matches the dominio in the Display From address. A typical DMARC recod looks like the following:
_dmarc.example.com TXT v=DMARC1; p=reject; rua=mailto:repots@tu/tus/su/susdominio.com; ruf=mailto:foensic@tu/tus/su/susdominio.com
