Ну добавьте руками -j DROP для этого ip-адреса в -t raw PREROUTING и посмотрите. Так у этого postfix-mailcow должен быть лог, какие правила он добавляет/удаляет.

И вы, случаем, это безумный workaround не использовали (с iptables-save по крону): https://github.com/mailcow/mailcow-dockerized/issues/4658#issuecomment-118149...
