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
