DNS Report

The DNS Report (under Reports -> DNS Report) gives you a read-only view of a domain's email authentication records. It queries public DNS and reports what it finds. It is query-only: it never changes any DNS record.

What it checks

For a given domain, the DNS Report looks up:

RecordWhat it is
SPFSender Policy Framework (authorized senders)
DMARCThe _dmarc policy record (p, rua, etc.)
DKIMDKIM public keys for discovered selectors
MXMail exchanger records
BIMIBrand Indicators for Message Identification
MTA-STSSMTP MTA Strict Transport Security policy
TLS-RPTSMTP TLS Reporting

DKIM selector auto-discovery

DKIM keys live at selector-specific names, so checking DKIM normally requires knowing the selectors. DMARC Dashboard auto-discovers selectors from the DKIM results observed in your already-ingested DMARC reports, then queries those selectors for the domain. The more reports you ingest, the more complete the DKIM picture becomes.

How it queries

Lookups go to public resolvers (such as 1.1.1.1 and 8.8.8.8). The report reflects what those resolvers return at query time.

Read-only

The DNS Report never edits, creates, or deletes DNS records. To change a record (for example, to repoint rua= at your dedicated mailbox), use your DNS provider's dashboard or API. See Polling and Safe-Delete for what the dashboard does after reports arrive.
