How to change from GoDaddy mail server to my Hosting company's server
I have been going back and forth with SiteGround bc my email will not work. They think it is bc of GoDaddy's server, and the MX records of my domain are pointed to it. I tried to find where I could change the name of the server (SiteGround says it has to be changed on GoDaddy's end). I cannot figure out where to change the DNS. A designer set this up for me, but he is on vacation, help!
