Tools

9 tools listed at last check
  • check_domain Run the full email and DNS deliverability check for a domain: MX, SPF, DKIM, DMARC, DNS health, provider detection, and blacklists. Returns a letter grade (A+ to F, where specific weaknesses cap the grade), a 0 to 100 score, and every individual check with its RFC reference. Set include_smtp to also
  • 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.
