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) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# tailwart — Stalwart mailbox as a Tailscale sidecar (NO WAN presence).
|
|
#
|
|
# The container shares ts-stalwart's network namespace, so its only interfaces
|
|
# are lo and tailscale0. All mail ports listen on the tailnet only; the public
|
|
# edge is the separate caddy/ layer-4 proxy, which can run on another host.
|
|
#
|
|
# Prereq: the shared tailnet infra (Postgres the-record-prod, Redis
|
|
# slo-time-prod, Garage) must be up, and the stalwart role/db/bucket created
|
|
# (see README). Bring up: docker compose up -d
