Hi all,
I'm running into an issue with Mailman 3. Mails sent to a list are being held due to moderation settings — which is expected — but after approving them, they are not delivered to list members.
The message does not end up in the shunt queue, and nothing is delivered.
Here's what I see in the Mailman log:
Jul 30 16:12:23 2025 (213300) HOLD: mm@lists.example.com post from sender@sub.example.com held, message-id=<20250730141221.5VVrn%sender@sub.example.com>: The message is not from a list member Jul 30 16:12:39 2025 (213338) held message approved, message-id: <20250730141221.5VVrn%sender@sub.example.com>
In the mail log, I only see the message arriving — there's no sign of it being sent out.
Any ideas on what could be going wrong or where else I should look?
