Tools

• check_blacklist ~128 tokens
  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.
• check_dkim ~192 tokens
  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 ~115 tokens
  Check 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_domain ~142 tokens
  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 ~125 tokens
  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.
• dns_lookup ~189 tokens
  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.
• lookup_mx ~115 tokens
  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.
