Core Concepts

The DMARC/SPF/DKIM rules YADT implements, and why it scores things the way it does.

Multi-Tenancy & Row-Level Security (RLS) — how tenant isolation is enforced at the database layer.
DMARC Subdomain Policy Inheritance — why a subdomain without its own record isn't automatically unprotected.
How Reports Are Attributed to a Domain — matching report records to the right domain, not just the report's own.
SPF ~all vs -all: Conditional Mode — when a hard SPF fail stops being worth the risk.
Detected Domains: Finding Unregistered Senders — surfacing subdomains and DKIM selectors before they cause an incident, and the notifications bell that tells you about them.
How DNS Checks Are Scheduled — the sweep cadence and why unverified domains are never auto-checked.
Domain Rating: How the 0–100 Score Is Calculated — the weighted formula behind the single letter grade.
Ask AI — the opt-in button that turns an issue into a question for an AI assistant, and what it shares.
