Advice on how to straighten out a crappy ISP

[Bill Moran]

My ISP is Adelphia Cable Internet.

Their tech folks are incompetent, and their tech support is useless.

Their mail servers are broken and therefore any mail to @freebsd.org
bounces.  If you look at my headers, you'll see that I configured my
box to be its own mail relay and I'm able to send to the FreeBSD lists
(yippie!).

However, it's still a DHCP addy and there's no way of hiding that.
Thus, my emails are getting rejected by a lot of other people ...
most recently, I'm finding that RoadRunner's entire SMTP system
rejects me.

I am NOT paying for a static IP.  I don't need it, I have no need
or desire to run any servers on this box - I wouldn't even bother
to run my own mail relay if Adelphia would fix theirs so I could
use it.

When I try to talk to them, I get anything from "reinstall Windows"
to flat-out ignored.

Does anyone have any suggestion on how I can get them to fix their
worthless shit?  I've tried being nice.  I've tried being an asshole.
I have nothing to threaten with, as there are no other high-speed
providers in this area.
