On push to main send a repository_dispatch event to chatmail/docker with relay_ref, relay_sha, and relay_sha_short. This triggers docker-ci.yaml to build a new Docker image from the updated relay code, push to GHCR, and eventually run integration tests via cmlxc's reusable lxc-test workflow. Requires DOCKER_DISPATCH_TOKEN secret with repo scope on chatmail/docker. Also set workflow_dispatch to allow manual triggering of Docker builds from any relay branch via the GitHub UI.
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
