My understanding is that they started breaking the RFC by refusing mail
with null <> senders last week.

Based on past experience, I wasn't too surprised.

Doesn't look like they are doing this.

Another thing - verizon is fairly responsive and does have some clued people in there. I have forwarded this thread to a friend in Verizon's postmaster desk.
