## Tools (as reported by the server, not verified)

- `check\_email\_domain`: Check everything about a domain's email setup in one call: SPF, DMARC, MX, DKIM on common selectors, domain blocklists, MTA-STS, TLS-RPT and BIMI. Use it for a general question such as "is email set up correctly for example.com".
- `check\_spf`: Check a domain's SPF record: whether it exists and is valid, how many of the 10 allowed DNS lookups it uses, and how its all mechanism treats mail from servers that are not listed.
- `check\_dkim`: Check a domain's DKIM public keys in DNS. With a selector \(the s= tag of a DKIM-Signature header\), checks that selector's key; without one, probes common selector names. Finding no key on common names does not prove DKIM is missing: selectors cannot be listed from DNS.
- `check\_dmarc`: Check a domain's DMARC record: whether it exists and is valid, its policy \(none, quarantine or reject\), alignment, and where reports are sent.
- `lookup\_mx`: Look up a domain's MX records \(its incoming mail servers\), their IP addresses and reverse DNS. DNS only: it does not connect to the mail servers.
- `dns\_lookup`: Look up DNS records of a name. Type ALL \(the default\) queries A, AAAA, CNAME, MX, NS, TXT, SOA and CAA; any single type can be asked for. An IP address gives its reverse DNS \(PTR\) lookup.
- `check\_blacklist`: Check whether an IP address or a domain is listed on public DNS blocklists \(DNSBLs\). A domain is checked on domain blocklists only; to check a mail server, give its IP address.
