DMARC record requests no aggregate reports

There is no rua address, so you receive no data about who sends as your domain.

Check your own domain

What causes this

The rua tag is the address receivers send daily aggregate reports to. Those reports are the only broad view you get of which systems send mail using your domain and whether they authenticate. Without rua, a p=none policy accomplishes nothing at all — it neither enforces nor informs.

What it breaks

You cannot tell whether raising the policy would break legitimate mail, which is exactly the information needed to move beyond p=none safely.

How to fix it

Add an rua address to the record.

  1. Choose a mailbox or DMARC reporting service to receive the reports.
  2. Add rua=mailto:that-address to the DMARC record.
  3. If the address is at a different domain, that domain must publish an authorisation record — see the external reporting finding.

Example record

TXT · _dmarc
v=DMARC1; p=none; rua=mailto:dmarc-reports@yourdomain.com

Specification: RFC 7489 — DMARC
