Hello,

The following document is a good place to start, and includes information about configuring RDNS:

How to Keep your Email out of the Spam Folder - cPanel Knowledge Base - cPanel Documentation

You can contact your provider and request they setup RDNS from your server's IP address to your server's hostname.

Thank you.

I already have a pending feature request, but it would be interesting if cPanel would automatically use a smart host in these situations. If OP is on 20 black-lists he'll need to clean house first, but we find ourselves on random black-lists for no good reason, we then manually route the mail to dnsexit so it can be delivered to edwardjones, rackspace or whoever is giving us trouble.
