Relay software is definitely lacking and not updated often. I looked into it and it seems everything is done through the Linux command line. 
It's takes experience to understand the Linux command line. I still struggle sometimes with it. 
I couldn't even find the areas where the reports go to. You literally have to search through the command line for everything. I'm going to try a different relay and see if I can find an easier one.
Well when relay administrators open their relays to the internet without spam protections it's expected.
