DNS Server issue

I was helped by Micheal N. on a ticket with reference number *** on a query I had regarding DNS servers. My HostAfrica DNS servers were not pointing to the correct destination, and this resulted in my HMail Plus emails not working. I logged a ticket and Micheal N. responded promptly and with a conclusive and clear, step by step answer, and after I followed his instructions, my HMail Plus emails were immediately fully functional.
