About this report
This report grades the email and DNS setup of gpmobility.autos against the relevant RFCs. Each check links to the standard behind the rule. A high grade means the common causes of spoofing and poor deliverability are covered. A grade is not a guarantee that every message reaches the inbox.
Frequently asked questions
What does the grade mean?
The grade summarizes how completely the domain implements the core email authentication and DNS standards. A and B mean the main protections (SPF, DKIM, DMARC, valid MX) are in place. Lower grades flag gaps that make spoofing easier or hurt deliverability. A missing MX record caps the grade at F, a weak SPF all-qualifier caps at D, and no DMARC caps at C.
How fresh is this report?
A report is a snapshot from when it was last scanned, kept as a shareable link. If you are fixing your setup, use the Re-scan button to run every check live again.
Why is the SMTP section still loading?
The live SMTP probe connects to the mail servers from a dedicated prober, which takes a few seconds and runs separately from the DNS checks. The results stream in when ready. If SMTP was not requested for this report, that section stays empty.
I own this domain and want to stop scan.mx checking it.
Domain owners can block scanning by publishing a DNS TXT record; see the opt-out page.
