Record health
Scan A, MX, NS, SOA, SPF, DMARC and CAA in one query. Get a health score and fix-it hints.
Enter a domain to score records, mail authentication and RFC basics.
This page is not a propagation map. It reads apex records through one public resolver: nameserver count, apex CNAME clashes, A/AAAA, MX, SOA timers, SPF (RFC 7208 lookup limit), DMARC policy, common DKIM selectors, CAA and DS presence.
The score starts at 100. Critical issues (apex CNAME, missing NS, SPF +all) cost more than informational notes (no CAA, no IPv6). For country-by-country consistency use the home-page DNS Check. For the sending IP against spam lists, open IP Blacklist.
SPF lists who may send as you. Multiple v=spf1 records or more than ten DNS mechanisms cause permerror. DMARC p=none only monitors; quarantine or reject stops spoofed mail. DKIM selectors vary by provider; this tool probes common names.
Missing SPF/DMARC makes blacklist listings more likely. İsim Kayıt corporate mail is set up with the matching TXT records.
