Email auth & domain security

Someone is sending email as you.
Find out who.

Most anti-phishing tools watch for domains impersonating you. This watches the other half — your own domain being used to send mail. Monitelia validates DMARC, SPF, DKIM and BIMI, then ingests real aggregate reports and maps the countries sending mail in your name.

The four records

Published isn't the same as protected

Most domains have some of these. Far fewer have them configured so they actually stop anything.

DMARC

Is the policy present, and is it actually enforcing? We flag p=none — published but permitting — as the gap it is, and score the escalation path to quarantine and reject.

SPF

Parsed and counted. The 10-lookup limit in RFC 7208 is silently exceeded by most growing stacks, and once you cross it SPF stops evaluating.

DKIM

Probed across the common selectors, plus any you add — so a rotated or half-configured key doesn't sit broken unnoticed.

BIMI

Checks the record and whether a VMC is referenced — the piece that puts your logo next to authenticated mail in supporting clients.

The differentiator

A map of who's spoofing you

Publishing a DMARC record with rua= means mailbox providers send you daily reports on every source using your domain — and almost nobody reads them, because they arrive as zipped XML.

Monitelia parses them for you: source IP, resolved country, message volume, SPF and DKIM pass rates, and what the receiver did about it — rendered as a country map and a table of top senders. That's how you find out a bulletproof host in another country has been sending invoices in your name.

Domain posture

The infrastructure checks that quietly cost you

Certificate expiry

Issuer, validity window, days remaining and SAN coverage. Alerts at 14 days, before the outage — not during it.

DNSSEC

Whether your zone is signed at all, checked daily.

TLS version

What your server actually negotiates — not what the config claims.

Blocklists

Your resolved IP against Spamhaus, SpamCop and Barracuda. Being listed silently is how deliverability dies.

Records-only checking needs no setup at all. Ingesting aggregate reports requires pointing your DMARC rua= at an inbound address — a one-time DNS edit, documented in setup.

Check your domain in about a minute.

Add a domain on the free plan and see your DMARC, SPF, DKIM, BIMI and certificate posture scored — before deciding anything.
