Verifying DMARC with dig and Online Tools

Verifying DMARC with dig

The dig tool is a good way to verify your DMARC record is being returned correctly by our DNS servers. To learn more about dig, see How To Use dig.

To verify the DMARC record, query for the TXT record at the fully qualified domain name where the TXT record lives.

For example, on the domain hostname.com, you can get the TXT record using the following query:

dig +short _dmarc.hostname.com TXT

This will return a result like:

"v=DMARC1; p=quarantine; pct=100; rua=mailto:aggrep@hostname.com; sp=reject; aspf=r;"

If no result is returned, verify that you added the TXT record with the correct subdomain. Remember, the Name field in DNSimple should not include your domain name, otherwise it would create a record at subdomain.yourdomain.com.yourdomain.com.

Verifying your DMARC with an online tool

Verify your DMARC with an online tool like this one from MX Toolbox. This verifies that you have set up a DMARC record, lets you know which tags and values your record contains, and alerts you to any problems with your record.

Monitoring DMARC

DMARC sends daily reports to the email specified in the RUA tag to provide an overview of email traffic. These reports are sent in XML format, and can be difficult to read — we recommend using a free tool, like Postmark’s reporting, to provide a weekly, human-readable report.
