Monitoring that explains what happened
Email domain monitoring for SPF and DMARC records
Track published email-domain records and investigate missing or conflicting configuration. DNS checks do not establish that a delivered message passes authentication.
Inspect published policies
Review SPF record count, DMARC policy and aggregate-reporting configuration. Resolve duplicate SPF records using your legitimate sending providers instructions.
Validate real delivery separately
Use a real message header to inspect SPF, DKIM and DMARC results and alignment. A DKIM selector lookup establishes key presence, not signature validity.
Common questions
Does this send a test message?
No. Email-domain monitoring inspects public DNS records and does not send mail on your behalf.
