NOT ENFORCED

8 checks · 1 failed · 3 advisory · MX: Mimecast

The policy is p=none: 100% of this domain's mail is exempt from any DMARC decision, and that has been the posture since before the bulk-sender rules took effect.

CheckWhat the record says
! SPF record Present but ends in - — unauthorised senders are soft-failed, not refused.
✓ SPF under the lookup limit 4 of 10 permitted lookups.
✓ DKIM keys discoverable 2 of 18 standard selectors present.
✓ DMARC record Present.
× Policy is enforced p=none. The record satisfies a checklist and protects nothing — anyone can still send as this domain.
✓ Aggregate reports collected rua= present. Someone can see who is sending.
! Transport security published No TLS-RPT. No MTA-STS. Inbound TLS failures are invisible to the sender.
! BIMI logo No BIMI record, and the policy is not strict enough to be eligible.

What this scan cannot see

Alignment is not verifiable from DNS alone: whether a message is aligned depends on the From header at send time. Custom DKIM selectors cannot be enumerated either — only the 18 standard ones. That gap is why a report taken from aggregate reports, not DNS, is what an enforcement change should be based on.

Sender inventory and enforcement fix — CAD 1,250

Six files, delivered in two business days: the sender inventory, the verdict sheet, the copy-paste DNS change set for your provider, a dated enforcement plan, the fourteen-day aggregate-report read, and a day-30 attestation you can hand to a security questionnaire.

CAD 450 if you would rather apply the records yourself. There is no call — the report is the conversation. Full refund if the change set is not delivered in two business days.
