Hey guys, im a complete newb at SSL and basically everything else with this project. I am hoping you can help me. I actually used SSLforFree for my cert instead of letsencrypt because I wasnt exactly sure how to use letsencrypt.
So I am following the 2014 mail server setup guide on arstechnica. I purchased a domain to test with, and I’m just trying to learn here (not actually going to leave this mail server running or use it). I have it setup on a vultr VPS with ubuntu 18.04
The guide covers using certs from another CA. I have accomplished getting both the private key and the cert into the correct directory and now I am trying to create my chain cert. However, the “name” of the file, which in the guide is downloaded with wget, is from the other CA’s website. What Im trying to figure out is if it matters what I name the cert file, since I am just using it to make a chain anyway. (seeing as how all teh other cert names had proper server names, Im assuming the file name does matter) I can make the file, and paste the data into it, but I just not sure about the name. Here is the guide im using, and the instructions im stuck at are a few paragraphs from the bottom.
I could really use some direction if anyone is willing to point! thanks!!.
