Over-engineered play stack for infinidim.net — Stalwart wired into the shared
Postgres + Redis + Garage S3 over the tailnet, with no WAN presence. Public
mail ports are fronted by a separate caddy-l4 layer-4 proxy (caddy/) that can
run on any tailnet host tagged tag:reverse-proxy — decoupled from the mailbox.
- docker-compose.yml: ts-stalwart sidecar + stalwart, backends via MagicDNS
- config/config.toml: PG (data/fts) + Redis (lookup) + S3 (blob) strawman
- caddy/: xcaddy build with caddy-l4, JSON layer-4 mail proxy, own compose
- acl-snippet.hujson: tag:stalwart owner + backend/edge grants
- .env.example + gitignored .env (pulled from shared infra)
