Different server for emails and website
Hello. I built a website for my client and I want it to host it in digitalocean. My client doesn't want to change his email platform and he wants to keep it in the previous server. So I thought to add an A RECORD on the previous server to point to DigitalOcean's one.
Ok this is easy. But I don't know that to do in the domain's nameservers. I'll keep the present nameservers or I should add DigitalOcean's? And also what should I do in DNS setting of the droplet?
