A simple question to this community, what are you self-hosting? It’s probably fun to hear from each-other what services we are running.
Please mention at least the service (e.g. e-mail) and the software (e.g. postfix). Extra bonus points for also mentioning the OS and/or hardware (e.g. Linux Distribution, raspberry pi, etc) you are running on.
I didn’t have a guide available, so I created one just now here.
From the Protection side you are right. My setup does not have DDoS protection or the WAF offered by Cloudflare, but as I didn’t need that (yet) I’m fine with it. Would be something to look into, should I even get enough traffic on my pages that machine could not handle it.
