You might be right.
I couldn't get to 63.24.130.230, but from my person server (which has
no relation to VZ's network):
patrick@p8.bos/1:59PM% telnet relay.verizon.net 25
Trying 206.46.232.11...
Connected to relay.verizon.net.

This is much better than I originally thought.
Still think they should allow sending mail from their network though. :)
