What this configuration means

Each section below is shown because the observed records match its condition. The explanations are reviewed text selected by the data, not generated from it.

No DMARC policy applies

No valid DMARC record was found for ezviz7.com, and the RFC 9989 discovery walk found no organizational policy to inherit. Receivers therefore have no instruction for mail that fails SPF and DKIM alignment, which means the domain can be used in the From field of a spoofed message without any policy asking for rejection. Publishing even a monitoring policy (p=none) with an aggregate reporting address starts producing evidence of who sends as the domain.

A single mail exchanger

Inbound mail depends on one published host, mail.ezviz7.com. That host belongs to Self-hosted or other, which provides its own redundancy behind the name. A single MX is normal for hosted mailbox providers and a risk for self-hosted ones.

No common DKIM selectors found

None of the selector names commonly used by major platforms resolve under _domainkey.ezviz7.com. DKIM has no enumeration mechanism, so the domain may sign with a selector this check does not try; absence here is not proof that DKIM is unused. It does mean no platform with a conventional selector is publicly visible.

No transport-security policy

ezviz7.com does not publish MTA-STS, so senders negotiate TLS opportunistically and fall back to clear text if an attacker strips the upgrade. Publishing TLS-RPT first, then MTA-STS in testing mode, adds transport protection for inbound mail without risk to delivery.

Change history

No change has been observed since the first snapshot on 2026-09-19. The domain is re-checked regularly and a new entry appears here when any record above changes.

How to read this report

The grade summarizes two records only: A means an enforcing DMARC policy with SPF hard fail; B enforcing DMARC with SPF; C monitoring-only DMARC or a weak SPF qualifier; D one of SPF or DMARC missing; F neither published. It is a prioritization aid for the public control plane, not a statement about deliverability, reputation or the security of the organization behind the domain.

DMARC policy is discovered with the RFC 9989 DNS tree walk, so a subdomain with no record of its own is reported with the organizational policy it inherits. DKIM selectors are discovered from common names only; a domain may sign with selectors this check does not try. Everything on this page comes from public DNS as observed on 2026-09-20; caches and split-horizon DNS can show different values elsewhere.
