[MM3-users] MM3 not processing some mails from specific user

Any idea what that could be? Here are some logs:

I don't see anything in either the MTA log or the sample message. However the sample message is incomplete, I assume the rest is an HTML version of the plain text MIME part. It's unlikely but possible that there is a defect in the rest of the message.

Have you checked the Mailman logs? Typically they end up either in /var/log/mailman or /var/lib/mailman/log (or variations on those appropriate for your installation)

Also, check the shunt queue, typically in /var/lib/mailman/queue/shunt. This is where Mailman puts messages that contain errors that didn't prevent delivery but make processing impossible.
