I’ve created a Terraform module to automate Mailcow installation on Vultr. Give it a look here and file issues here. Its beta quality at best, but I’d love some feedback from any one that tries it out. I’ll put in some time polishing up the docs and examples over the next week or so.
I’ve been working on another module to install on AWS if that is of interest to anyone. You can find it here but its pre-release still so I wouldn’t recommend trying it.
