I registered a domain and changed the primary and secondary nameservers to point to my web host.
I now want to setup an email address but the web host says I have to do this at the "domain provider". My argument to them is that I can't do this at the registrar since the nameservers have changed which redirects all domain traffic (including MX) to the web host and they have to setup the email addresses.
To add my argument, the domain provider did allow me to edit MX records but only if the nameservers were with them. The ability to edit MX was removed once I switched primary/secondary nameservers to the web host.
Am I correct in this assessment? Am I missing something relating to the MX records?
