holger krekel 4b79606d49 feat: per-relay image caching, static IPs, and parallel deploy
Switch from a single localchat-relay image to per-relay cached
images (localchat-test0, localchat-test1) and add a DNS image
(localchat-ns).  Assign static IPs via a fixed incusbr0 bridge
subnet (10.200.200.0/24) so containers always get deterministic
addresses.

Container launch is split into 'incus init' + device-override +
'incus start' to set the static IP before boot.

Deploy runs in parallel via _run_cmdeploy_parallel(), which
captures output per-relay and shows progress lines.  Tests now
run in both directions (test0↔test1, test1↔test0).

publish_image() returns bool (True if published, False if cached)
so lxc-test can report cache hits.

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
