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 vali.starlink.edu -- as interpreted by Gmail. I believe there should be an additional DKIM-Signature: inserted (added) by vali.starlink.edu (or mail.pearsoncomputing.net) to correct Gmail "550 5.7.1 Unauthenticated email is not accepted from this domain" bounces.
