Indeed, Gmail rejected the list server's attempts to deliver it: Error: 552 5.7.0 This message was blocked because its content presents a potential security issue. Please visit https://support.google.com/mail/?p=BlockedMessage to review our message content and attachment content guidelines. a66si14491710pfb.91 - gsmtp If there hadn't been objections, this would be similar to CFJ 1905: https://faculty.washington.edu/kerim/nomic/cases/?1905 But slightly different, since the message was dropped by list subscribers' mail servers rather than the list server itself.
