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.
Most of this stuff runs on my server at home (ASRock J4105-ITX, 8 GB RAM , 250 GB SSD, 18 TB HDD). The mail server and the blog run on a cheap VPS (1 vCPU, 2 GB RAM, 20 GB SSD). Both servers run NixOS.
Quick question: have you thought about hosting Radicale and filebrowser instead of NextCloud? I think that would be definetly lighter on your system.
Also: I have read lots of mixed opinions whether mailservers should be selfhosted - what is your take on this? Do you know about problems reaching the big player mailservers?
