Actually that's debatable - the SORBS DUHL is about IPs assigned to hosts/people/machines dynamically. We do not list addresses where the ISP have sent the list explictitly saying 'these are static hosts, but they are not allowed to send mail' - similarly we do list hosts in the DUHL where the ISP has said 'these are dynamic but we allow them to send mail' - it's about the people using the SORBS DUHL for their purposes, not for helping ISPs getting around the issue of whether to use SORBS as a replacement to port 25 blocking.
