[Dxspider-support] please help for unsuscribe

Hello all I need help for unsuscribe. I have 3 mail boxes suscribed to the list, receiving 3 copies of every mail. No way to leave the list using address dxspider-support-leave@dxcluster.org Any admin can see if exists solution or the only one is apply a filter in my email client for dump the mails? As I can see, I arn't the only one having this kind of problem, any solution can help many of us. Responses type "you can send a mail to dxspider-support-leave@dxcluster.org for exit from the list" are useless. Regards Rick LU9DA
