We operate in one of the older RoadRunner areas and have been providing
that service for years for "hobbyists". 100:1 any such hobbyist can
find that equivalent anywhere in the world.

Yes, and the only times we've been blacklisted was when our customers
turned out to be running open relays on their shiny new NT boxes.
Many cable modem systems provide static addresses. This gets really
sticky, because lately we've been getting a lot of spam from them. The
local abuse/postmaster@isp merely disclaims responsibility and forwards
complaints to the operator. Just local here in Portland Maine there
are some 3000 businesses on cable; as more and more of them start
running their own SMTP servers and plugging in CDROM email databases
this problem will mushroom. The damage a spammer can do from dialup
is nothing compared to what he can do on a 2M cable connection with
a linux box and powerful MTA.
The only entity that can do anything is the ISP. They have to be
responsible for the mail their customers send.
