Hi,
What do you think is wrong? Note the log says that the message was refused during the SMTP connection. Normally if the message is refused during SMTP, there is no delivery status notification (DSN) sent to the -bounces address, the message is just returned to sender. Mailman generates an artificial DSN which the system uses to keep track of SMTP-time rejections. The message you included looks like one of those to me.
I was wondering about example.com, I thought it would have used the list where the issue appeared or at least SITE_ID or SERVE_FROM_DOMAIN.
My impression was (without looking into the logs) that the mails got classified as spam and rejected because the were sent from example.com.
Best Regards Bjoern
