Looking at Lisi's bounce results (and seeing that it was a message from

headers was _mine_ going out of _my_ ISP to the listserver.  There is
_no_ DKIM-Signature: from the outbound operation from the listserver.
So, any DKIM checking on that email's headers would be invalid.  I.e.,
trinity@... is NOT authorized to send an email from -- as interpreted by Gmail.

I believe there should be an additional DKIM-Signature: inserted (added)
by (or to correct Gmail
"550 5.7.1 Unauthenticated email is not accepted from this domain"

-- especially the last post there.

Anyway, that'sa what I'm a'thinkin...
