Received chain, ESP fingerprints, unsubscribe and auth headers
As received, minus the delivery side: the archive's own addresses appear as [recipient] and its mail servers as [receiver], the Received chain stops where the sender handed off to us, signatures are left out, and unsubscribe links are trimmed to their host.
