Tools

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.
shallow
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.
shallow
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.
shallow
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".
shallow
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.
shallow
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.
shallow
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.
shallow
