Postfix is rejecting mail from an address that should be allowed in. The

The IP address for cox.net is correct.

It said SENDER address rejected... cox.net was the CLIENT address. The SENDER was <[EMAIL PROTECTED]>

Post output of postconf -n

Are you doing SAV (Sender Address Verification)? You should NOT use SAV for general mail reception, you should only do SAV probes for sending domains you control and/or have gotten explicit permission to do SAV for.

I've added the 'someserver'.com and hotmail addresses to
/etc/postfix/rhsbl_sender_exceptions with an explicit 'OK'.

Which address of the three is unverified, and how do I fix this
problem?

Disable SAV... you will never be able to receive mail from the big vendors (gmail, hotmail, yahoo) if you are doing SAV probes all the time...

So
