DMARC is not configured

DMARC
Domain-based Message Authentication, Reporting and Conformance
DKIM
DomainKeys Identified Mail
SPF
Sender Policy Framework

The domain has no published policy for handling mail that fails aligned SPF and DKIM.

The concept

What is DMARC?

Domain-based Message Authentication, Reporting and Conformance joins SPF and DKIM with visible From-domain alignment. It also tells receivers how to handle failed mail and where to send aggregate reports.

Recommended action

What to do next

  1. Create a reporting mailbox or use a DMARC reporting service.
  2. Publish a TXT record at _dmarc using p=none and a rua address.
  3. Review reports before moving to quarantine or reject.

When this result may be wrong

DNS caches may retain a recently added record. DMARC also depends on alignment, not merely SPF or DKIM passing.
