j4n 825831ee81 fix(cmdeploy): replace resolvconf/systemd-resolved with static resolv.conf, purge
1e376f7 explicitly installed resolvconf to fix DNS breakage after
ff541b8 disabled APT recommends. But resolvconf adds dynamic resolver
management and is unnecessary on a server. Similarly, systemd-resolved
competes for /etc/resolv.conf.

Write a static resolv.conf with unbound as primary and 9.9.9.9 as
fallback. Purge resolvconf, stop and mask systemd-resolved to prevent it
from overriding the static configuration.

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
