Impossible to Whitelist IPs/Domains

Hi Verizon Support,

My company is an email services provider company

On of my customer recently tried sending an e-mail to a Verizon customer and got a bounce back message stating the server's IP was blocked for spam.

So I submitted a whitelist request at:

and get a response that our IP will not be whitelisted...the exact message is:

"Your IP has been blocked because of spam issues or because your ISP indicates that it is dynamically assigned"

I tried multiple times but got always the same answer.

Further, I have checked various blacklists to see if my servers/IPs are blocked by them, including using, and they are not listed in any of them

Is it possible to escalate this issue  to a Verizon agent ? to be contacted by private message ?

In fact i need at least to whitelist an IP/Domain and if it's possible whitelist a network subnet.

I will give these informations by private mesage cause i would prefer not display these informations publicly

Best Regards
