Why haven't we seen a Terraform setup of containerized email hosting on VPS yet? I feel like it would be really good because it could do the DNS setup with IaC, and therefore also support moving between providers if necessary. I know the risks of taking over someone's old IP to host email on of course, but with TF you could quickly re-deploy somewhere else until you find an IP that is good.
