Open-source tool that audits a domains email authentication and DNS security, including DNSSEC, with no account

Web appmvpfreeglobal

An open-source web app that scans a domain's DNS and email authentication settings—SPF, DKIM, DMARC, DNSSEC, and related records—and reports passing checks, warnings, and issues; it detects the email platform from DNS records and requires no account or data storage. Intended for IT and security administrators, domain owners, and DevOps or deliverability teams, it helps find misconfigurations that can enable spoofing or delivery problems and summarizes them in one audit.
