Observed evidence
Observed by .auDO
These fields describe the public evidence .auDO records for this signal where available.
Interpretation
How to read this signal
This signal is useful as public evidence of visible posture or change, not as a conclusion on its own.
Why it matters
MX records can help contextualise visible mail routing and mail provider movement when interpreted with DMARC, SPF, TXT records and inferred email provider.
What change may indicate
MX changes may indicate mail provider migration, routing changes, filtering changes, reseller configuration, administrative cleanup or operational maintenance.
Limits
What it cannot tell us
MX presence does not prove that email is actively used, safe or fully protected. MX records alone cannot prove risk, compromise, negligence or intent.
Observations are descriptive records, not risk scores, allegations or evidence of compromise.
