Attempts to connect to port 25 of 'relay.verizon.net', which is the MX for
verizon.net, causes the mail server to close the connection with the
message:

What a surprise, you made up a procedure and it didn't work.

"571 Email from 71.175.54.72 is currently blocked by Verizon Online's
anti-spam system. The email sender or Email Service Provider may visit
http://www.verizon.net/whitelist and request removal of the block."

That address is within Verizon Internet Services own CIDR block:
71.160.0.0/11, so why is it blocked? It belongs to a Verizon customer.

It's blocked because that's not the correct method for sending mail
through Verizon. You did what a malware script would do rather than
what a sane person would do, so Verizon treated you like malware.

What's going on? Does the router assign a different IP address to each user
on the local network? That doesn't seem right.

How could the router not assign a different IP address to each machine
on the local network? What else could it do?

Or am I all wet about that Verizon MX server?

Yeah, Verizon's instructions like a smart human being rather than
thrashing around randomly like a piece of malware.
