What the controls accomplish

SPF

Authorize senders

SPF lists the servers and services permitted to send mail using the envelope domain.

DMARC

Set enforcement

DMARC tells receivers what to do when SPF and DKIM alignment checks fail.

RUA

Observe failures

Aggregate reports reveal legitimate services, unauthorized sources and rollout mistakes.

ALIGN

Protect identity

Alignment connects authentication results to the domain visible in the message’s From address.

Privacy note

The domain is sent from your browser to Google Public DNS. AIOTEC does not request mailbox credentials or email contents.

Results describe public DNS configuration and are guidance, not a guarantee of deliverability or protection against impersonation.
