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.
