What is DMARC? DMARC, short for Domain-based Message Authentication, Reporting & Conformance, is a standard that enhances SPF and DKIM. It communicates a policy to mailbox providers, guiding them on how to handle emails failing SPF, DKIM, or both, claiming to be from your domain (potentially spoofed).
STEP 1: Figure out if you have a DMARC
To check if your domain has a DMARC record, please use this website Dmarcian for free, and follow the steps below:
If see a message like this:
It means that your domain does have a DMARC and you do not have to do anything.
STEP 2: What should you do if you do not have a DMARC?
If you lack a DMARC record, here are the steps to add one to your domain DNS records.
Implementation Steps:
1. Visit your DNS hosting provider and create a TXT DNS record.
2. Choose TXT as the record type.
3. Set the host value as '_DMARC.' Adjust if needed, ensuring it includes your domain (e.g., '_dmarc.domain.com').
4. Craft your DMARC record and add it to the DNS TXT value. A basic DMARC record looks like: 'v=DMARC1; p=none;'.
5. Save/submit and verify the correct addition of your DMARC record in DNS.
