I have some insight into what is happening here. L-Soft just updated
listserv v 16 to do exactly what you describe (I belong to L-Soft’s
site manager and list owner groups). The patch causes listserv to
check for a DMARC DNS record, and if one exists with p=reject it
rewrites the FROM field in the header with what you describe. If the
originating IP does not have a DMARC record or has one and does not
have p=reject listserv ignores it. So either Google uses listserv or
they read the listserv lists also and copied it.
Either way, it is a very ugly workaround.
Why ugly? It strikes me as minimally intrusive (and one of the options
for the current Sympa patch).
