How to Create a DMARC Record

DMARC stands for Domain-based Message Authentication, Reporting, and Conformance. DMARC is one of the authentication methods in email designed to protect domain emails from unauthorized email addresses or what we commonly call spoofing emails.

Spoofing is a type of email attack by forging email headers, to make it appear as if the email address was sent from a valid or legitimate email. Email spoofing is commonly used for spamming or phishing activities.

DMARC data format

DMARC is created with the TXT record method. Here is an example of a DMARC record that you can use:

"v=DMARC1;p=reject;pct=90;ruf=mailto:postmaster@dmarcdomain.com"

The description of the sample record above is as follows:
