Email provider
Email provider is a best-effort classification inferred from public MX and related mail-routing patterns.
What .auDO infers
A provider label derived from visible mail-routing evidence
.auDO uses MX records and known public patterns to group visible email infrastructure. The supporting MX evidence remains the direct observation.
Technical fields
Why it is inferred
Provider patterns make mail infrastructure legible
Why it matters
Provider inference supports aggregate concentration and movement analysis across the fixed panel.
What visible change may mean
A change may reflect migration, filtering changes, reseller arrangements, routing updates, cleanup or maintenance.
Interpretation limits
Inference is not a provider declaration
The classification may be incomplete or ambiguous and does not establish a direct customer relationship, endorsement, service quality or internal arrangement.
