Ruston Mail
Ruston Mail is an unofficial desktop client for Proton Mail, written in Rust. Its three-pane interface lets you read, organize, and send mail without an embedded browser.
It ships with ruston-cli, a command-line client for the same Proton account. Ruston Mail is not affiliated with or endorsed by Proton AG.
Compatibility: Uses the C library of the system (may need glibc 2.35 or later)

Usage
Ruston_Mail is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. Awesome!
AppImages are single-file applications that run on most Linux distributions. Download an application, make it executable, and run! No need to install. No system libraries or system preferences are altered. Most AppImages run on recent versions of Arch Linux, CentOS, Debian, Fedora, openSUSE, Red Hat, Ubuntu, and other common desktop distributions.
This AppImage uses the C library of the system and may need glibc 2.35 or later. It does not run on distributions that use a different C library (such as musl on Alpine Linux) or an older glibc.
Running Ruston_Mail on Linux without installation
Unlike other applications, AppImages do not need to be installed before they can be used. However, they need to be marked as executable before they can be run. This is a Linux security feature.Beware! AppImages are usually not verified by others. Follow these instructions only if you trust the developer of the software. Use at your own risk!
Download the Ruston_Mail AppImage and make it executable using your file manager or by entering the following commands in a terminal:
chmod +x ./*.AppImageThen double-click the AppImage in the file manager to open it.
Sandboxing Ruston_Mail
If you want to restrict what Ruston_Mail can do on your system, you can run the AppImage in a sandbox like Firejail. This is entirely optional and currently needs to be configured by the user.
Updating Ruston_Mail
If you would like to update to a new version, simply download the new Ruston_Mail AppImage.
The Ruston_Mail AppImage also can be updated using AppImageUpdate. Using this tool, Ruston_Mail can be updated by downloading only the portions of the AppImage that have actually changed since the last version.
Integrating AppImages into the system
If you would like to have the executable bit set automatically, and would like to see Ruston_Mail and other AppImages integrated into the system (menus, icons, file type associations, etc.), then you may want to check the optional appimaged daemon.
Note for application authors
Thanks for distributing Ruston_Mail in the AppImage format for all common Linux distributions. Great! Here are some ideas on how to make it even better.
Pro Tips for further enhancing the Ruston_Mail AppImage
Please consider making the Ruston_Mail AppImage self-contained, so that it does not depend on the C library of the system and runs on more distributions: ship the C library including its loader (ld-linux-*.so.*) and use it to launch the application, or link statically.
Thanks for shipping AppStream metainfo inside your AppImage. Please open a pull request on https://github.com/AppImage/appimage.github.io/blob/master/data/Ruston_Mail if you have changed it and would like to see this page updated accordingly.
