Append Docker build-and-test steps to the existing split CI workflows (test-and-deploy.yaml and test-and-deploy-ipv4only.yaml) Each workflow now has: - build-docker job: builds image with buildx, pushes to GHCR on push - Docker deploy section stops bare services, installs Docker on VPS, copies ACME/DKIM to bind mounts, reuses chatmail.ini from bare-metal step, pulls GHCR image, starts container with docker compose - Tests run inside container via `docker exec chatmail cmdeploy ... --ssh-host @local` — no CHATMAIL_DOCKER env var needed - id: wait-for-vps added to VPS wait step for conditional guards The build-docker and deploy jobs run independently.
Chatmail relays for end-to-end encrypted email
Chatmail relay servers are interoperable Mail Transport Agents (MTAs) designed for:
-
Zero State: no private data or metadata collected, messages are auto-deleted, low disk usage
-
Instant/Realtime: sub-second message delivery, realtime P2P streaming, privacy-preserving Push Notifications for Apple, Google, and Huawei;
-
Security Enforcement: only strict TLS, DKIM and OpenPGP with minimized metadata accepted
-
Reliable Federation and Decentralization: No spam or IP reputation checks, federating depends on established IETF standards and protocols.
This repository contains everything needed to setup a ready-to-use chatmail relay on an ssh-reachable host. For getting started and more information please refer to the web version of this repositories' documentation at
