cliffmccarthy e20226f331 refactor: Simplify interface to Deployer.install()
- In the current code, the only class using the interface that sets
  need_restart() from the return value of the install() method was
  IrohDeployer.  That interface was created when the install method
  was a static method, but now it is an instance method with access to
  'self'.  Therefore, we don't need to pass anything up to the caller
  to have them set the attribute, we can just set it.
- Revised IrohDeployer.install() to set self.need_restart directly,
  rather than returning a value.
- Revised Deployment.install() to ignore the return value of the
  deployers' install() methods.
- need_restart is still present in the base Deployer class to ensure
  that it is always defined, even when classes do not set it in a
  constructor.  Apart from this initialization for convenience, there
  is no longer any specific exposure of need_restart in the interface
  of the Deployer class.
- In general, install() methods should use 'self' as little as
  possible, preferably not at all.  In particular, install() methods
  should never depend on "config" data, such as the config dictionary
  in self.config or specific values like self.mail_domain.  This
  ensures that these methods can be used to perform generic
  installation operations that are applicable across multiple relay
  deployments, and therefore can be called in the process of building
  a general-purpose container image.

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
