Server's IP address can't get whitelisted


It's my first time i send an email to a verizon email account from this server IP And in my email report log, it shows the following error:

"SMTP error from remote mail server after initial connection: 571 Email from is currently blocked by Verizon Online's anti-spam system. The email sender or Email Service Provider may visit and"

I go to that website to request a delist, but, im getting this email:

"After investigation, Verizon Online Security has determined that e-mail from your IP address will not be allowed access to the Verizon Online e-mail domain due to one or more of the following reasons:
Your IP has been blocked because of spam issues or because your ISP indicates that it is dynamically assigned"

Also, i used to check if the server was blacklisted, but the result was that it's not blacklisted.

The server ( is secured, it has CSF firewall. Hope you can help me to get this IP whitelisted.

Thanks you in advance
