Question

Naming my Droplet | Naming Mail/Web Server (with consideration for PTR)

I’m currently following Ars Technica’s guide “Taking Email Back” and I need your advice. I have one class 1 TLS from StartSSL and it is for mail.bringlove.org. But StartSSL’s documentation says, The base domain bringlove.org will be included by default in the Alt Name section. I assume this means that both http://mail.bringlove.org and http://bringlove.org will be covered by the certificate. But how to plan for PTR?..

Considering PTR Records/Reverse Lookup, SPF Record, and things like DKIM, what would you name your droplet, mail.bringlove.org, or simply bringlove.org? This is a small personal website, and I’ll be hosting the site and the mail server in the same ubuntu-nginx/mariadb droplet. The most important thing to me is that my email be accepted by whoever I send it to, and with PTR in mind I know that it should make a difference how I name the server. And of course I don’t want the hassle and cost of segregating mail and site on different servers. It doesn’t help that I have no experience doing this, but I just don’t want to go through all this setup for nothing (again ;).

If you were me, with my goals and my TLS certificate, how would you name your droplet?

Hello,

You want your PTR to match the server hostname. So if your servers hostname is mail.bringlove.org then you want to name your droplet mail.bringlove.org so it matches the servers’ hostname.
