No post = no bounce for that day = no score increment.
It seems that my real misunderstanding is even more fundamental. I was expecting Mailman to retry sending an email if it received a bounce for that adress. I thought it would retry until either no new bounce was received anymore or the bounces threshold was reached. But this really is a misunderstanding, right?
