IP listed on Spamhaus PBL list?

Not my own, but an associate has his TWC IP address listed as can be seen here:

The cause has been traced to a Chinese IP of:

The result is that outbound emails sent through a third-party SMTP server are blocked as spam by some, not all, email recipiant's servers. This began suddenly after years of proper function. At this point, I cannot tell whether spam was generated spoofing his domain and IP, or if it actually was routed through his third-party SMTP server. His domain provider claims there are no issues associated with his account.


Does anyone have any idea as to the proper and expediant method for resolving this?

Change to a different router manufacturer and you'll get a different TWC public ip

Re: IP listed on Spamhaus PBL list?

Unfortunately, the new IP would still be in the range of and remain blocked by the PBL. It would seem that TWC/Charter must be the one to drive the boat getting their IP range removed from the Spamhaus Project PBL list and to resolve this issue completely. The question is just how to get this information to someone that CAN and WILL accomplish that.

Re: IP listed on Spamhaus PBL list? is listed on the Policy Block List (PBL)

Outbound Email Policy of Time Warner Cable/Road Runner for this IP range:

It is the policy of Time Warner Cable/Road Runner to share with other entities lists of our dynamic IP address space. While Time Warner Cable/Road Runner does not currently forbid customers from sending out mail directly from such space, it recognizes that others may wish to refuse mail from such space, and so Time Warner Cable/Road Runner makes that space known to others to facilitate their enforcement of their policies. Customers finding their mail refused by others due to a PBL listing should send their outbound mail through the outbound mail server designated for them; see for more information on the servers' names.
