perfect, so basicly your isp is stopping spam via no dns ?
reminds me of tele-danmark and piratebay dns blocked, while it was
working with no problems if one just have own dns servers, now thay have
paid for the content shareing, but curt in lyngby still ask isp to block
piratebay, hellios :=)
lesson learned is curts should block domains with the registras, not on
dns
