Our Company Blocked by Verizon Online's Anti-spam System

I am having a problem with my Company e-mail not able to conect with Verizon customers. I get the following error: 

    host relay.verizon.net []

    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 http://www.verizon.net/whitelist and request removal of the block. 170511

We did have a spam problem before but a Security Company called Site Lock fix it for us and now we are clean. I do try the white list form from Verizon and it does not work because the responce e-mail I receive is you are being block because of Spam. Everywhere else I am not being blocked and I keep checking my system to make shure we are clean from spam. Please he lp me get my company off your blacklist, Thank you. {edited for privacy}
