External authorisation builder

Construct and review the DNS name used to authorise an external aggregate-report destination.

Domains entered here are not submitted to DMARC Analyst.
External authorisation recordTXT nameexample.com._report._dmarc.rua.dmarcanalyst.comTXT valuev=DMARC1;

This constructs the standards-defined name but does not change or query DNS. DMARC Analyst provisions its managed authorisation from the account dashboard.

Use the result carefully

DMARC decisions depend on public DNS, receiver behaviour and real authentication results. Use this output as a focused diagnostic aid, then confirm changes through DNS and subsequent aggregate reports.
