Hi it sounds like there is a dns problem with the appliance.
The CSVB needs dns to retrieve the reputation score of the appliance. Senderbase works by querying repuation servers to get the reputation of the incoming host attempting to send mail to your CSVB. If it cannot connect then you will see lots of 'no score' on repuation or 'no domain information'.
To try and diagnose this i'd suggest:
1. Login to the appliance and use the cli or gui to run a trace to see what happens when you try & get a reputation for the host 209.196.13.10
This should have a bad reputation - if you don't get one then the senderbase query is failing to get the score. DNS ports should be open for both directions to your DNS server or root DNS server.
2. Review the dns settings on your appliance - i'd suggest you use root dns to troubleshoot and update your firewall to use the root dns servers.
Cheers
