Also imagine your domain being joe-jobbed.  You, as an innocent bystander,
then get hammered by Verizon as they try to do a lookup on possibly
millions of incoming mails.

It's just not a very sane way to reduce their spamload.  It's something
I'd expect from a smaller ISP, but I would have imagined by now that VZ
would have the money to go with something like Brightmail, or develop
something in-house like AOL.
