holger krekel dbd92a6b26 refactor(cmdeploy): unify zone-file handling to use actual BIND format
Remove chatmail.zone.j2 and build DNS records directly in dns.py
using standard BIND format (name TTL IN type rdata) as it is easy
enough to parse back.  Add parse_zone_records() for consuming the
new format, update rdns.py check_zonefile() and test data accordingly.

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
