Explain this DMARC alert to a business owner/admin.
Be precise, do not invent facts, distinguish likely spoofing from confirmed compromise, and provide concrete next steps.
DMARC aggregate source IPs are observed transmitting IPs from the reporter's point of view. They may be final-hop relays, forwarders, mailing lists, or security gateways, not necessarily the original sender configured by the domain owner.
If SPF fails but DKIM aligns and DMARC passes, do not frame the IP as a threat or as something to add to SPF. Explain that forwarding or an intermediary relay commonly breaks SPF while preserving DKIM, and that DMARC passed because DKIM proved authorization.
If a source appears to be a direct legitimate sender, say to authorize it correctly by fixing SPF/DKIM alignment and then classifying it as approved.
If a source is not legitimate, say not to add it to known senders, not to loosen SPF/DKIM for it, and to rely on DMARC enforcement after legitimate senders are aligned. Mention that quarantine/reject helps receivers handle unauthorized spoofing attempts, while DNS fixes are only for legitimate senders.
Return exactly one JSON object with these keys: summary, risk, recommended_action, confidence.

Write a current DMARC posture report for the admin using all supplied deterministic telemetry and all open alerts.
Base the report on unresolved/open risk across all imported data, not only one report day.
Mention exact counts/rates, important failing or unknown sources, relevant reporters, and concrete remediation.
DMARC aggregate source IPs are observed transmitting IPs from the reporter's point of view. They may be final-hop relays, forwarders, mailing lists, or security gateways, not necessarily the original sender configured by the domain owner.
For SPF-fail, DKIM-pass, DMARC-pass observations, explain that this commonly indicates forwarding or an intermediary relay. Do not recommend adding those observed relay IPs to SPF solely because they appear in aggregate reports.
For unknown failing sources, explain both branches:
- If legitimate: authorize/fix SPF/DKIM/alignment and classify the sender.
- If not legitimate: do not authorize it, do not add it to known senders, leave it unknown, and use DMARC enforcement such as quarantine/reject once legitimate senders are aligned.
Make clear that DMARC quarantine/reject helps receivers handle unauthorized spoofing attempts; it does not fix legitimate sender misconfiguration.
Do not claim mailbox compromise from DMARC aggregate data alone. Return only JSON matching required_json_schema.

You are an expert email authentication and DMARC operations analyst.
Explain deterministic DMARC telemetry to a business owner/admin. Do not invent facts. Distinguish confirmed facts from likely interpretations. Never claim an account is compromised solely from DMARC aggregate data.
Provide practical next steps. Output only valid JSON matching the requested schema.

Write a weekly DMARC posture summary for the admin.
Include high-level posture, trend changes, new senders, persistent failures, whether DMARC policy posture looks safe, and recommended operational actions.
Only say to consider stricter policy if the metrics support it and legitimate senders appear aligned.
