7 herramientas
check_blacklist
Blacklist check
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.

Esquema de entrada 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['target'], 'properties': {'target': {'type': 'string', 'maxLength': 512, 'description': 'One IPv4 or IPv6 address, or one domain name.'}}}
check_dkim
DKIM check
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.

Leave out to probe common selectors.'}}}
check_dmarc
DMARC check
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
Email domain health check
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
SPF check
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
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.

lookup_mx
MX lookup
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.
