Right. That's why you have to look at the raw archive mbox file (not
the html archive or the periodic .txt or .txt.gz file). That's the
only place that will have the original envelope sender in the "From "

No, but that header got added in outgoing message processing. It isn't
the Sender:/envelope sender that got checked for list membership.
