Thanks for your analysis. The bounces we got (not only from
GMX/Web.de) only complain about RfC-violation, but didn't show why.
We now disabled bounce-detection if it is related to that.
We'll check how to be more strict in accepting these kind of mails
now.
Yours,
Cord, Debian Listmaster of the day
