Currently we strip the DKIM-Signature header in the OpenDKIM final.lua script after validation of the signature. We sign all messages upon submission, but we do not verify messages which are from a local account and delivered to another local account. This corrects the problem and ensures that the plaintext headers of a local to local delivery are sanitized the same as a message received from another server. The functionality in final.lua to strip the DKIM-Signature header can now be retired.
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
