I believe this is a slightly controversial topic, at least from what I have gathered so far. Some say its best to leave the server on to spare the life time of the spinning rust. Other seem to prefer to save power and boot the server off each night. So wanted to chip in and hear what folks here do and why do what you do.
Bonus question; Do you guys have a UPS? Is it a must have for a homelab, or does it just depend on the usecase?
Do you selfhost email too?
Currently yes. I have a bit of a non-standard setup though. Like a business contract with my internet service provider, which includes a few perks that are required to send mail and are missing on a normal residential internet connection (static ip, dns reverse pointer). And generally 95% of people recommend not to do email yourself. I might change in the future. Back in the days it was a few bucks more a month, but they increased prices substantially. Either I move my mailserver to a VPS or save me some time and effort and switch to some email service like everyone else.
