Custom nameservers, email vps and website vps

Just posted the question without body…sorry for that. <br> <br>1) So we will be hosting clients, for the moment every client will be getting his own VPS with Vesta, can i use custom nameservers for their websites ? I mean for all clients use the same nameservers(using our own domain, not client’s). <br>Is it better if we use one vps specifically for this purpose? <br> <br>2) For our own emails i want to use a different VPS so in case our website’s vps goes down for any reason we will still be able to receive and send emails…i will use live.com but it needs to add mx etc so i think it will be safer to use a separate vps…is that right ? possible ? <br> <br>Any help or suggestions about how we could setup/arrange this will be more than appreciated as any links to tutorials. <br> <br>Cheers

Sorry for the multiple messages…forgot to mention that we have multiple websites(6-7) using multiple domains and we have emails with all of those domains , so i need the email vps to handle all of those.

Hello Stelio, <br> <br>About question 1, you can either setup your own DNS or use DigitalOcean DNS services. See the link for how to setup your own DNS ttps://www.digitalocean.com/community/articles/how-to-install-the-bind-dns-server-on-centos-6 <br> <br>Now about question 2, you can install them all together which is not recomended. My suggestion is 3 different droplets, 1 running your website and mail server databases, 1 for your website and one for your mail server.
