I am at a loss for what to do.

I'm taking spam messages at the rate of 6,000 per day from a specific e-mail
address linked to several Verizon DSL IP addresses.

I have sent numerous logfiles to both security@ and abuse () verizon net and
have received no response.

I have spoken with their tech support numerous times and both they and their
supervisors say they can not help, they claim the e-mail addresses are the
only recourse.

Define "a specific e-mail address linked to several Verizon DSL IP
addresses."

If all the email is originating from just a few DSL IP addresses, just add
those IPs to your access list (assuming you're running sendmail).  If not,
you'll need to be rather more specific as to what's going on.

Yes, this is a bandage on the symptom rather than a solution to the real
problem, but until you can convince someone at Verizon to cut those IPs
off, it will at least stop the spam.
