"DNS Doctor (https://dnsdoctor.dev) — DMARC monitoring plus SPF, DKIM and DMARC diagnostics for any domain. Scan email authentication, find SPF lookup-limit problems, check DKIM and DMARC, generate validated DMARC records, monitor DMARC RUA reports and new senders, and move from p=none to quarantine on a scan's evidence and to reject on report evidence. Free domain scans and a free monitoring trial. Every DNS change is human-approved. Fix records are generated deterministically and RFC-validated, never guessed by AI; SPF is diagnosed, never rewritten. Twenty tools: scan a domain (SPF, DKIM, DMARC, MX, DNS health, blacklists, domain and TLS expiry), read the stored report, look up a domain's registration (registrar, expiry, nameservers, locks), build a validated DMARC upgrade or a DMARC record from scratch, validate a pasted DMARC record, count SPF lookups, audit SPF includes, check a DKIM selector, check a record on the domain's own nameservers, check global propagation from six vantage points, check reverse DNS, parse a DMARC aggregate report, build the hardening pack for a non-sending domain, hand the owner a monitoring sign-up link, and for signed-in operators read the monitoring alert log and the enforcement-readiness verdict. Three account tools add a domain to monitoring, run the ownership check and read the records to publish; today they hand the owner the same sign-up link. The assistant never signs the user in, never emails on their behalf, and never applies a DNS change: it explains the findings and presents each record for the human to publish."

"Check, fix and monitor your domain's DNS and email authentication. Look up records, see whether a change is live across six locations, read registration and expiry, and diagnose SPF, DKIM and DMARC, with engine-validated DMARC records when the evidence supports a change. Send a test email to a single-use address and see how that real message authenticated: SPF, DKIM and DMARC alignment, message hygiene and blocklists, with an itemized score out of 10. Connect a DNS Doctor account to monitor the domains you verify: DMARC aggregate reports read for you, alerts on new senders and record changes, and whether the report evidence supports the next DMARC policy step, including what is still blocking it. You publish every record yourself.\n\nScan a domain for email authentication (SPF, DKIM, DMARC), mail routing (MX), DNS health, blacklists and domain and SSL certificate expiry. Read A, AAAA, CNAME, MX and TXT records, including SPF and DMARC, from the domain's own nameservers, see whether a change has reached resolvers in six locations, check reverse DNS for a mail server, count SPF lookups, audit the third-party includes an SPF record trusts, and read a domain's registration: registrar, expiry, nameservers and locks. Check which look-alike names close to a domain are registered and resolve, stated as facts and never labelled malicious; any takedown report is filed by the owner from the DNS Doctor dashboard.\n\nDMARC records are generated and validated by a deterministic engine that follows the RFCs. The AI writes the explanation, never the record. SPF is diagnosed but never rewritten, because a changed SPF record can silently cut off a real sender. Nothing is applied to your DNS: you publish every record yourself.\n\nConnect your DNS Doctor account to work with your monitored domains from ChatGPT: add a domain, check its ownership record, review watched look-alike names with their threat scores, and read the alerts DNS Doctor raises for record changes, expiry, blacklisting, registrar or nameserver changes and new email senders seen in DMARC reports. It also tells you when that report evidence says it is safe to move DMARC from none to quarantine and then to reject."
