Verizon.net email admin?

[Chris Adams <cma () cmadams net>]

Anybody Verizon.net mail admins around?

I have a downstream customer on a newly-deployed IP allocation that
can't get to pop.verizon.net (connections just time out).  She can surf
elsewhere, she can take the same computer to another location (different
IP block) and it works, so it appears something on Verizon is filtering
out the IP space (from 107.190.192.0/20).

Thanks.
