This issue led to a GSOC proposal in order to improve things upstream: * https://lists.mailman3.org/archives/list/mailman-us...@mailman3.org/message/IHU7QQ56TIQCLQIAVRSUEWYOEX3TO4NJ/ * https://gitlab.com/mailman/hyperkitty/issues/208
If it gets picked up, the issue might eventually be fixed upstream. For now, there is https://gitlab.com/mailman/hyperkitty/issues/207 which is at least a good compromise. Stefan
