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 also self host a mail server but I don’t think I’d every put anything super important through it. Right now I use it to send emails from the services I run (plex, file sharing, etc). It’s a fun little project but if you want something reliable it’s going to get pricy very quick.
