-One of our first explorations of this possibility was adding built-in support for [DeltaChat](https://delta.chat/), the secure decentralized messenger, within the Butter ecosystem. This means, in the base ButterBox firmware image, we include the [MadMail server](https://github.com/themadorg/madmail), an open-source server project that is an instance of the DeltaChat ["Chatmail Relay"](https://delta.chat/en/2023-12-13-chatmail) concept. The MadMail server is built using Ansible as part of our [Churn firmware image building process](https://guardianproject.dev/butter/churn/src/branch/main/ansible). It is then configured by the box admin during the setup [using the interface MadMail installer](https://guardianproject.dev/butter/butter-portal/src/branch/main/install_madmail.py).

 ButterBox also bundles the latest release of the [DeltaChat Android APK](https://delta.chat/en/download) in the image with each release. This ensures new people can use DeltaChat even without access to an internet-based app store. In the future, we plan to also include the desktop software, a local web interface, and possibly an iOS binary, for jailbroken or sideload capable devices.
