DNSAuthFix

DNSAuthFix is a web app that audits and repairs email authentication (SPF, DKIM, DMARC) by turning messy DNS into a guided, testable change plan. It connects read-only to your DNS provider, detects common breakages (SPF 10-lookup limits, missing DKIM selectors, DMARC misalignment, unsafe “p=none forever” policies), and generates provider-specific DNS records with a safe rollout checklist. It continuously monitors propagation and real-world outcomes using mailbox placement signals and DMARC aggregate reports, then flags regressions after vendor changes (new ESP, new CRM, domain move). This is a traditional app with light AI assistance: AI explains findings in plain English and drafts change tickets for IT, but the core value is deterministic validation and guardrails. It’s built for teams that want fewer deliverability fires and fewer expensive consultants.
