And why would you want to do that? There's quite a few out there
using dynamic IP's for their servers. I would even go so far as
to say that the legal uses by far outnumbers the spammers.
This is an important point and that is why whitelisting and exclustion lists
are integrated into DynaStop. Statistically, the number of legal dynamic IP
address servers is roughly 10% to 15%. The number of provisioned dynamic IP
blocks where the ISP has explicit policies against direct mail servers are
significantly higher (85% average). Cox, RoadRunner, Qwest, AOL, PacBell are
just a few that will cut service to an account running an illegal (in term
of their TOS) server. Cox actively scans customers computers looking for
such services (clearly spelled out in their TOS).
Its not legal if the user signed a TOS/AUP that forbides such actives. Nor
is it legal for spam zombies to infect uneducated users. DynaStop has made
significant procress in this area.
DynaStop can work from procmail allowing indivdual users to control how they
whant dynamic IP addresses handled without site wide issues. Global or
local, the benifits are quite substabtial in the large picture.
