This is a walkthrough for configuring your DNS settings with “DMARC” in your domain provider. The steps below for configuration should apply to whatever sending service you use.
DMARC (Domain-based Message Authentication, Reporting, and Conformance)
- First, you will need to login to your domain provider. (This may look slightly different for your domain provider, but the steps will be the same). I used “Namecheap” for this walkthrough. Select “Domain List” and choose the domain you’re configuring. Then click “Advanced DNS Settings” and you will see your records.
- Next, you will create a new “TXT” record
- In the “Host” field, you will input “_dmarc”
- Next, navigate to “https://dmarc.postmarkapp.com/” You will use this service to generate your DMARC
- Input an email into the “Your Email Address” field (This should belong to whoever will be monitoring your DMARC reports
- Input your domain name (example.com) into the “Send Reports about this Domain” field
- Copy and paste the DMARC provided by postmarkapp into the “Value” field of the “TXT” record that you created.
- Once you’ve pasted the generated DMARC into the “Value” field of your “TXT” record, change the “p=none” to “p=reject”. This will instruct receiving servers to reject mail sent using your domain that doesn’t pass SPF and DKIM checks.
- Make sure to save your changes! You have successfully set-up DMARC. Congratulations!
Having DMARC in place used to be just a recommendation, but in today’s email infrastructure, it’s imperative to have it configured correctly. Modern spam filters often don’t let emails through at all if DMARC is not set-up. (Be aware that you may need to wait up to 72 hours for your DNS settings to update.)
