Domain status
Verification confirms the RUA destination is present. It does not test whether every sender passes DMARC or whether every mailbox provider will send reports.
Parent domains and subdomains
Registeringexample.com covers:
example.commail.example.comnews.example.com- Deeper names such as
transactional.mail.example.com
notexample.com, and registering mail.example.com does not cover its parent or sibling domains.
Subdomains normally inherit the parent DMARC record. The parent’s sp tag controls the subdomain policy when present; otherwise the p policy applies.
You do not need to register every subdomain separately when they report to the parent domain’s assigned address.
Use more than one report destination
Therua tag can contain multiple comma-separated mailto: destinations. This lets you keep an existing mailbox or another DMARC service while evaluating JetEmail.
Important DMARC tags
Move safely towards enforcement
1
Start with visibility
Use
p=none for a new policy while reports identify legitimate and unexpected sources. This policy monitors failures but does not ask receivers to block them.2
Fix legitimate sources
Configure aligned DKIM wherever possible and correct the SPF return path for every authorized sender. Confirm forwarding and mailing-list behavior before making policy changes.
3
Introduce quarantine
Move to
p=quarantine, optionally with a lower pct during rollout, and watch the failing volume and receiver dispositions.4
Enforce rejection
Use
p=reject; pct=100 only after all legitimate high-volume sources have reliable aligned authentication.
