Message Origin Analyzer
Paste raw message headers and this tool correlates the recorded identity, routing, authentication, ARC, and provider-infrastructure evidence already present in them, entirely in your browser.
Results describe evidence recorded in the headers only -- correlated identity, routing, authentication, ARC, and provider signals -- not the message's physical or human origin, and not a determination of whether the message can be trusted.
This analysis runs in your browser. Your pasted headers are not sent to Collabovizion, saved as history, or included in analytics. Headers can contain private addresses, internal hostnames, IP addresses, and Message-IDs; redact them when they are not needed for the diagnostic.
Results
Some header evidence was truncated to keep this analysis bounded.
Origin summary
Visible sender identity
Each field below is reported header evidence, shown separately. No single field is treated as the authoritative sender.
Reported authentication identity
Authentication-Results summary
No Authentication-Results field is present in the analyzed header block.
Authentication-Results records what receiving systems reported. This tool does not independently establish which authserv-id should be trusted.
Likely originating platform
Likely sending platform: Unknown from the available recorded evidence
Recorded provider evidence indicates this sending platform:
Multiple possible sending platforms
Recorded evidence supports more than one provider and does not provide a defensible basis to select one.
Recorded infrastructure sequence
Oldest recorded evidence first. Earlier hops may have been added before the message entered a trusted mail system and can be forged.
No infrastructure sequence evidence is recorded.
Authentication chain
A conceptual identity/authentication chain built from recorded evidence, not an independent cryptographic-verification chain.
ARC / intermediary evidence
ARC evidence is reported from the headers and is not independently cryptographically verified by this tool.
Forwarding / alignment assessment
Forwarding assessment
Visible-From alignment
