DMARC record generator

Build a DMARC TXT record by picking policy, alignment, percentage and reporting addresses, sequenced from monitoring toward enforcement.

The record builds as you pick.

A blind jump to p=reject can block legitimate mail: any sender that has not been aligned yet, including invoices or CRM mail from a provider nobody told you about, stops delivering. The staged order exists for that reason. The generator assembles the record locally and validates the addresses and percentage; it does not check whether the addresses accept mail, and publishing at your DNS host stays a manual step.
