[MM3-users] All messages to a new list/domain shunted from "in" queue with no logged exceptions

OK -- my turn to ask a question...

I created a new domain and lists in my (functioning) Mailman 3 install.

Messages to these new lists are successfully delivered via LMTP to Mailman and then disappear. They are in the shunt queue, with a source queue of "in". There are no exceptions logged in my mailman.log.

An example from a qfile: {   '_parsemsg': False, 'envsender': 'noreply@[domain].com', 'lang': 'en', 'listid': '[listname].[domain].com', 'original_size': 2654, 'received_time': datetime.datetime(2023, 11, 25, 14, 0, 6, 968185), 'rule_hits': [], 'rule_misses': [], 'to_list': True, 'version': 3, 'whichq': 'in'} Unshunting the message has no effect, and no logs are generated.

Any suggestions?

Thanks, --Jered
