Are you aware that even if your domain name doesn't send emails, it could still be hijacked by sneaky cyber villains for phishing or spoofing? But hey, fear not! There are secret weapons in the form of DNS TXT records that can come to your rescue. These records set up rules for mail servers, making it tough for those bad guys to mess with your domain.

So, what's the deal with DNS TXT records? Think of them as magical scrolls that domain wizards (admins) can use to jot down important instructions for email guardians (servers) to follow.

Here are the heroes of the story: SPF, DKIM, and DMARC records. Let's meet them one by one!

SPF Records: Imagine SPF records as the bouncers at an email party. They check the guest list (IP addresses and domain names) and kick out anyone not invited. It's like saying, "Hey, only cool cats on this list get to send emails from my domain!" The secret code looks like this:

v=spf1 -all

Translation: "Hey server, this is an SPF policy, and if anyone not on the list tries to crash the party, show them the door!"

DKIM Records: DKIM records are like the royal seal on a letter. They confirm that the sender is who they claim to be. Each domain has its own secret key, and DKIM checks if the message's signature matches the key. It's like whispering, "Only the real deal gets my stamp of approval." Here's a peek:

Name: * Type: TXT Content: v=DKIM1; p=

Translation: "Hey server, this is my DKIM policy. If there's no signature, then it's not from me!"

DMARC Records: DMARC records are the guardians of the inbox. They make sure emails follow the SPF and DKIM rules. If any email tries to sneak in without playing by the rules, DMARC sends it packing. Check out this command:

Name: Type: TXT Content: v=DMARC1;p=reject;sp=reject;adkim=s;aspf=s

Translation: "Hey server, this is my DMARC policy. If an email fails SPF or DKIM checks, boot it out of here!"

With these records in place, your domain is like a fortress, protected from email marauders. And guess what? Setting them up is as easy as casting a spell with your Rocket Domains Planetary DNS settings inside your Mission Control Dashboard.

So, what are you waiting for? Go forth, brave domain owner, and shield your emails from the forces of darkness!
