Remove the custom certmon timer (polling via sha1sum every 60s), replaced by the deployer's tls-cert-reload.path unit (inotify). chatmail-init.sh: inject TLS_EXTERNAL_CERT_AND_KEY env var into chatmail.ini at startup if not already present. docker-compose.yaml: remove CMDEPLOY_STAGES, CHATMAIL_NOSYSCTL, TLS_EXTERNAL_CERT_AND_KEY from base environment (set in init script or via override file).
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
