Riiiigghht. From the ORDB web pages, "stores IP-addresses of verified open SMTP relays." The verification is done by a series of automated tests. They also attempt to notify the postmaster at the listed site when they become listed, and removal is as easy as requesting to be retested.
Frankly, I wouldn't believe anything a Sprint customer service rep tells me. It's their job to make you believe that any problem with service is not theirs.
