Wietse, Yes, this is submitted locally.
When a local submission is rejected by header/body_checks then it should be returned to sender, not get stuck in the queue. The message will get stuck in the queue if you set: internal_mail_filter_classes=bounce
In /etc/postfix/main.cf.default internal_mail_filter_classes is not set to anything. Thanks, Rich
