Do not blacklist a clean mail server

Our company is running a clean mail server at: 80.188.97.251

Symantec is blacklisting whole IP range of our ISP: 80.188.97.0 – 80.188.103.255

Everyday I have to submit a request for delisting at: ipremoval.sms.symantec.com

Can you whitelist our mail server?

Thank you
