DMARC monitoring and RUA report analysis

DMARC does not end when the record is published. Aggregate reports show who sends as your domain, which sources align, and where stronger policy could disrupt legitimate mail.

A published policy still needs observation

A malformed record may leave a domain open to impersonation or disrupt legitimate delivery. RUA reports contain receiver-level aggregates, and manual interpretation becomes difficult as source count and volume grow.

Authorized sources

Classify known senders without conflating them with unknown services.

Alignment

Observe SPF and DKIM outcomes relative to the domain visible to recipients.

Policy

Track `none`, `quarantine`, `reject`, and percentage rollout before enforcement changes.

From aggregate XML to reviewable decisions

LuminaKite receives RUA through an assigned alias, normalizes aggregate data, and presents trends. The assistant supports source classification and readiness review; it does not edit DNS or guarantee every receiver will report.

Receive

Process aggregate XML while avoiding unnecessary retention of raw attachments.

Explain

Connect volume, source, disposition, and authentication outcomes.

Prioritize

Separate legitimate failures, forgotten services, and signals worth investigating.

Manual analysis versus monitoring

Unpacking a report and reading XML is useful for learning or investigating one case. Monitoring adds continuity, classification, and history. Moving to `reject` still requires owner validation and a gradual rollout.

Frequently asked questions

Does LuminaKite change my DMARC policy?

No. It analyzes evidence and may suggest a record; the customer retains control of DNS.

Do RUA reports contain email messages?

They are aggregate reports, not message bodies. They may contain source IPs and authentication domains and are protected as tenant data.

Should I move directly to p=reject?

No. Identify senders, fix alignment, and advance gradually to avoid blocking legitimate mail.

Turn DMARC reports into decisions

Centralize RUA and review alignment before tightening policy.
