you will need to check if you have a valid rDNS set and DKIM signed emails.

DKIM & SPF Manager

File /etc/opendkim/TrustedHosts don't exists!

What to do next?

try contacting your hosting provider for assistance with rDNS.

Make sure OpenDKIM is installed on your server because I just did a fresh install using Centos-Webpanel instructions and it didn't install OpenDKIM with the email packages thus causing same issues of the OpenDKIM files don't exist. Of course CWP Admin probably already knows this but would rather point you to someone else because issue is clearly not on their end of packages not installing correctly. Honestly though we can't really expect much from this product since it's cheap as in free.
