First off, Sorbs Lists ALL public IP addresses in their DUHL system. You are going to be listed in the PBL on spamhaus as well. This is because the PBL and others lists like it, are meant to prevent someone from running a MAIL SERVER from a residential IP address. That is all.
You should be listed in SORBS DUHL list, which notes - "
Usage classification (only important if you run your own mailserver.) |
Cox is not going to be able to just "CHANGE" your IP address, it's not that simple. It's handed off to your equipment on a 24 hr lease through a DHCP server which the customer service agents are NOT going to have access to. You can change the MAC ID of your router and get a different IP address, or replace the router and also get a new IP address.
Easier yet, connect your computer directly to the modem, bypassing your router and get a new ip address.
BUT, being on the DUHL list or the XBL or PBL lists, are not a problem, because again, they basically list you as a residential IP address, top prevent a mail server or relay from your IP address from sending or forwarding email directly to remote mail systems. It does not prevent you from using YOUR mail server, Cox/Gmail/Yahoo/hotmail/etc etc etc.
