Ask in plain words and get a clear answer, with the exact record to publish when a fix needs one.\n\nWith DNS Doctor you can:\n\u2022 Check email authentication: diagnose SPF, DKIM and DMARC, mail routing (MX), blocklists, domain and SSL certificate expiry, and which Gmail, Yahoo, Outlook and Apple sender requirements your DNS meets.\n\u2022 Check a DNS change: read A, AAAA, CNAME, MX and TXT records from the domain's own nameservers with a plain done, wait or edit answer, and see whether the change has reached resolvers in six locations on four continents.\n\u2022 Test a real email: send one message to a single-use address and see how it authenticated, with a score out of 10, a per-provider estimate of acceptance and, when available, of inbox placement.\n\u2022 Look up a domain: registrar, expiry, nameservers and locks, reverse DNS for a mail server, SPF lookup count and the third-party includes your SPF trusts.\n\u2022 Check whether your domain meets each mailbox provider's requirements for showing its logo in the inbox (BIMI), and which look-alike names close to your domain resolve, stated as facts and never labelled malicious.\n\u2022 Move DMARC to enforcement safely: DMARC records are generated and validated by a deterministic engine that follows the RFCs. The AI writes the explanation, never the record.\n\u2022 Choose a domain name: check up to 20 candidate names against their registries in one go. For a name with no registration, the result card can show the lowest standard 3-year total among the registrars we track for that ending, with a link to compare them. Nothing is sold and there are no buy links.\n\nMonitor the domains you verify by connecting a DNS Doctor account:\n\u2022 Website uptime checked from five locations on four continents (US West, US East, Brazil, South Africa, Germany), with an email when the site goes down.\n\u2022 DMARC aggregate reports read for you, alerts on new senders, record changes, expiry, blacklisting and registrar or nameserver changes.\n\u2022 When the report evidence says it is safe to move DMARC from none to quarantine and then to reject, and what is still blocking it.\n\u2022 From ChatGPT: list your domains with their next step, add a domain, check its ownership record, read the alerts, and review watched look-alike names with their threat scores.\n\nSPF is diagnosed but never rewritten, because a changed SPF record can silently cut off a real sender. ChatGPT never changes your DNS: you publish the records yourself.",
