About the DMARC Lookup tool

DMARC (Domain-based Message Authentication, Reporting, and Conformance) builds on SPF and DKIM to stop attackers from spoofing your domain. This tool queries the _dmarc TXT record, breaks down each tag, and highlights potential misconfigurations. For the strongest protection, aim for policies of quarantine or reject once you are confident legitimate mail is passing alignment checks.

Frequently asked questions

What DMARC policy should I start with?

Begin with p=none to monitor authentication without impacting delivery. Move to p=quarantine when confident, and finally p=reject for maximum enforcement. Track reputation with our Blacklist Checker to ensure legitimate messages are not blocked.

How do I configure DMARC on a VPS?

Create a TXT record at _dmarc.yourdomain.com with your DMARC policy, and ensure SPF, DKIM, and reverse DNS are set up. Need reliable infrastructure? Review our VPS benchmarks, compare plans with the plan comparison tool, and pick providers known for strong email deliverability.
