check_mx

Check the MX records of a domain: presence, hostnames, resolution, null-MX, and common misconfigurations.

check_spf

Check the domain SPF policy: presence, syntax, the all qualifier, and the 10-lookup limit.

check_dmarc

Check the domain DMARC policy at _dmarc: presence, policy strength (none/quarantine/reject), and reporting.

check_blacklist

Check whether the domain and its mail server IPs are listed on the Spamhaus (ZEN, DBL, ZRD, AuthBL), SpamCop, GBUdb and PSBL blocklists.

check_mta_sts

Check the domain MTA-STS policy (_mta-sts TXT and the HTTPS policy file, mode and MX coverage) and its TLS-RPT reporting record.

check_dnssec

Check DNSSEC validation and DNS health: delegation, nameserver count, SOA, and reverse DNS of the mail servers.

check_bimi

Check the domain BIMI record at default._bimi: the SVG logo URL, the VMC/CMC certificate, and the DMARC enforcement BIMI needs.

check_dkim

Check DKIM signing keys for a domain. Without a selector, common provider selectors are probed. Pass an explicit selector to look up that exact key at selector._domainkey.
