I'd normally start with Juno.com, but this never touched Juno.com. This is UU.Net spam.

Let's confirm IP addresses and other domains instead.

>whois cyberconnection.com
Cyber Connection (CYBERCONNECTION2-DOM)

   Domain servers in listed order:

   NS1.CYBERCONNECTION.COM      204.193.128.253
   NS2.CYBERCONNECTION.COM      204.193.128.252

OK, let's confirm that mail server IP address:

adams.cyberconnection.com ([204.193.128.253])
This properly resolves.


Let's check out an obviously bogus domain:

>whois asdfsfdsdf.com
No match for "ASDFSFDSDF.COM".

No suprises there.

Let's see where it resolves to:
mailhost.asdfsfdsdf.com (alt1.asdfsfdsdf.com(205.5.35.38))

That is not correct, but it does terminate somewhere in Sprint.

The UU.Net IP address resolves correctly:
1Cust55.max9.phoenix.az.ms.uu.net [153.35.229.183]

That was fun.
