A Terraform DNS moment

tl;dr: I stuck the IPv4 and IPv6 address of my VPS into an SPF record field text.

I manage my DNS with Terraform. This means that past domain registration and changing nameservers, I manage DNS with the Terraform command-line interface and git. Today I experienced a moment of happiness when two pieces of personal infrastructure fitted.

The scenario: I’m setting up a send-only email server on a VPS for Gitea notifications. If this works out well, I will consider using it for a newsletter. Doing this on a commercial cloud VPS means that my server’s IPv4 address gets a bad score. One way to improve on that score is to add an SPF record.
