- `check\_domain`: Look up a domain's live DNS and grade its email authentication: DMARC, SPF, DKIM \(common selectors\), MX, BIMI and MTA-STS. Returns each record, its status and the issues found, with a guide link per issue. A domain checked in the last few minutes is answered from that check \(cached, with its age\); p
- `generate\_spf\_record`: Build an SPF TXT record from the services and servers that send email for a domain, with an estimate of the DNS lookups it uses against SPF's limit of 10. Computes from the arguments only; nothing is looked up or stored.
- `generate\_dmarc\_record`: Build a DMARC TXT record and the host to publish it at, from a policy and the addresses that should receive aggregate reports. Notes what the record does not cover yet. Computes from the arguments only; nothing is looked up or stored.
