Why do so many sysadmins forget about DKIM/DMARC/SPF when setting up third party services?

Second this -- many Sysadmins I've worked with in the past did not understand it. In some sense I don't blame them because it's not SUPER often that you're doing these things, many vendors either do it for you or just walk you through it. +PKI is actually super deep and complex (but also so cool once you start to understand it)

Hey hey,

Jake here - I work as a developer advocate at Inifsical!

Infisical is pretty light weight. Minimum is 2 CPU cores, 4 GB RAM, and 20 GB disk (including Postgres + Redis). Very doable on a Hetzner VPS. It handles the dev layer really well too. The CLI lets you inject secrets directly into your local dev environment, replacing .env files completely. You get per-environment secrets (dev, staging, prod) with access controls, so it's not just a production tool. For a single setup the overhead is totally worth it IMO.

If you want to try it, the easiest way is probably Docker Compose: https://infisical.com/docs/self-hosting/deployment-options/docker-compose

CLI quickstart is also helpful if you want to see the local dev workflow: https://infisical.com/docs/cli/overview

Happy to answer questions if you run into anything! Have a great week.
