Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (7)

check_blacklistread-onlyCheck 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.
check_dkimread-onlyCheck 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_dmarcread-onlyCheck a domain's DMARC record: whether it exists and is valid, its policy (none, quarantine or reject), alignment, and where reports are sent.
check_email_domainread-onlyCheck 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_spfread-onlyCheck 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.
dns_lookupread-onlyLook 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.
lookup_mxread-onlyLook 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.
