Emails to verizon email addresses being blocked

I have seen other posts similar to mine in this forum so I'm hoping someone can help.

I am trying to send email to my customers and outbound mail from one of our mail servers to our customers is being rejected.

When we try to send a message we get the following message back:

571 Email from is currently blocked by Verizon Online's anti-spam system. The email sender or Email Service Provider may visit and request removal of the block. 170412

We have gone to the URL listed on the message and submitted the request to be whitelisted. When we do so we get the following email back:

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:
No Reverse Hostname associated with your IP address.

Our reverse DNS is correctly set up so we're not sure how to proceed with this.

Does anyone know how we can engage someone to help us get this block lifted?
