Hello,
I am not sure, if i can help you here. There is our help page with SPF
HERE and there is one about DKIM
HERE. Both are in czech, but u can use some translator.
Also, you can contact my colleagues on online chat
HERE every Monday - Friday from 8:00 AM to 4:30 PM. I am not sure, if there will be someone who would speak English, but you can definitely try it with translator assistance and they will answer all of your questions about Email profi.
Have a nice day,
Ivana
