How to interpret these observations

MX identifies the observed inbound mailbox or gateway. SPF includes identify services authorised to send for the domain. DMARC shows the published authentication policy. The dataset currently contains 2 populated signal groups for this page.

Observed deliverability context: based on the available observations, this page describes DNS configuration only. It does not represent a complete audit of ms.gov and does not prove that a particular message reaches the inbox or spam folder.
