Has Gmail been bouncing all list posts or just this one.

If just this one post, it could be a DMARC issue, although I think Gmail
gives a different reason for DMARC failures. Does your list apply any
DMARC mitigations? I.e. Privacy options... -> Sender filters ->
dmarc_moderation_action other than Accept.
