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 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.

        Verizon.net is blackholed on our networks two reasons:

        1.      The sheer volume of spam courtesy of their netblocks, and

        2.      The sheer audacity of their "whitelist" arrangement in
                which I and my customers have to give *them* our personal
                data to send their users e-mail...while verizon itself
                apparently does nothing to curb its outbound spam.

Since verizon.net was blackholed on our networks, our spam level has gone down significantly; almost as much as it did when we blackholed all of China.
