Hello Designbooth, 

Welcome to the Community page, 

So if none of them solutions have worked for you you will need to ask an IT expert about it and they will be able to guide you on it and get it resolved. 

I have asked and they are asking for more clarity. Are they TXT records?

Did you get the answer ?

This hasn't answered any of the questions above

Hello Designbooth, thanks for coming back to us here. We have answered your Question but I will repeat the answer again for you, we would suggest as previously consulting with an I.T expert to confirm this, it is more likely it is DNS.  For DKIM issues - its DNS.
