Free Tool / Email Trust

Is your domain spoof-proof?

Enter any domain and we'll check its live DNS records — SPF, DKIM, DMARC, MX, BIMI, MTA-STS and TLS-RPT — straight from your browser, then score its email health from 0 to 100 in plain English.

Input / DomainLive DNS

Checks run entirely in your browser using secure DNS-over-HTTPS (Cloudflare, with Google DNS as fallback). Nothing you type is sent to Xaccel or stored anywhere.

Server-side checks Full audit

Some checks genuinely need a server — they can't run inside a browser. The blacklist check runs live when this site is hosted on your server (dnsbl.php). The rest are included in the full audit — book a free assessment.

  • Blacklist reputation (DNSBL) — your mail server IPs checked against major blacklists (Spamhaus, SpamCop, Barracuda, SORBS and more). Runs live via the button above; worth up to +10 points (or −30 if listed) in the full score.
  • Mail server banner & TLS handshake probe — confirms your MX hosts actually answer on port 25/587 and negotiate modern TLS.
  • Hosted MTA-STS policy file — verifies the policy served at https://mta-sts.yourdomain/.well-known/mta-sts.txt matches your DNS record.
Raw DNS responses Technical detail

Every answer below came straight from a public DNS-over-HTTPS resolver — no Xaccel server involved.

Results will appear here. We'll check 11 DNS signals — from basic A/AAAA records to DMARC enforcement policy — then show you exactly what's working, what's risky, and what to fix first.

NEXT / EMAIL SECURITY

A score under 80 means spoofers can send email as you.

Our Email Trust Verification implements and monitors SPF, DKIM, DMARC (p=reject), BIMI and MTA-STS for you — and lifts inbox delivery by up to 40%. Paste a suspicious message into our Email Header Analyzer, or let us fix the domain itself.
