Verizon DOES do a sender verify.

The Verizon postmaster (Hi Paul!) does read this list. Maybe he will
respond to you off list. Since they started doing sender verification,
there has been some sporatic issues, most being resolved. There has been
several people bringing up similar problems in the private verizon
newsgroups. I'm pretty sure they are aware of these problems, but it is
possible that something is being triggered by your domain / ip block /
SMTP conversation.
