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 -- https://lists.debian.org
