Hello,
I work for an ISP, and we have allocated a /24 network that we own, to a customer of ours. Before receiving the /24 block (part of a larger subnet of IP addresses), there was some bad history assocated with the network, and due to this, many IP addresses from our network have made names for themselves on multiple email RBL blacklists.
We have a customer that is running a mail server on a /24 network that we have allocated to them, and have been able to clear their mail and gateway servers off of all blacklists except for Verizon's.
We have tried submitting our issues through the whitelist email ISP form, without any success, and have contacted multiple groups, both through our account team, and through recommeded contacts from the Verizon website, but our issue continues to be ignored and our customer's issue remains a problem for us.
This has been ongoing for months without any resolution, and while we could assign our customer a new /24 network, currently we only have networks within the same larger tainted network, so the issue is likely to remain even after assigning a new network.
Could a Verizon support rep please contact me privately regarding this issue, so we can get our customer's mail and gateway server de-listed from Verizon's RBL email blacklist?
Regards
