# 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 connections with strict TLS are accepted;
|
|
all messages must be correctly signed with DKIM and OpenPGP-encrypted with minimized metadata.
|
|
There are experimental exceptions for no-DNS relays,
|
|
which are allowed use self-signed TLS certificates
|
|
and which do not need to DKIM-sign their messages.
|
|
Unencrypted messages are allowed in neither case.
|
|
|
|
- **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.
