Harming or taking any sentient beings life is a wrong action, an evil action. It causes immense loss of wisdom, perspective, empathy and friendliness of your own mind; and it causes severe suffering to the beings that are subjected to your violent acts.

You are accumulating demerit by continuing these actions, there is truly no action worse than murder. The right time to stop is right now. I hope you stop ignoring the (now) diminished sense of wrongdoing, that made you okay with doing this.

Thunderbird application settings being client side, have a separate sync design, unrelated to thundermail. I don’t remember whether they finished it, but I do remember they were working on a sync feature.

I highly suggest Thundermail (tb.pro) if you wanna switch to a libre email provider. Mozilla hosts stalwart and their own libre mail client for you, along with providing 15 mail aliases and 3 custom domains, for a small price. I have been using it as my daily since past few months. I haven’t found any bugs despite it being in beta.

Make the transition if you feel like it. On youtube, there is a channel called System Crafters, who has various resources for understanding how to work with guix system, emacs and EmacsWM, if you are interested in the most unified operating system.

1. Superior Error handling and debugging(with Lisp REPL) thanks to Guile Scheme language.
2. Guile scheme is easier to write and understand. It has a mature ecosystem of libraries and standard programming constructs (macros, recursion, higher-order functions)
3. In Guix System, the package manager, the build system, and the system configuration are all written in the same language.
4. No systemd, Guix system uses GNU Shepherd. You define services directly in Guile Scheme. This allows for dynamic service manipulation, hot-swapping, and introspection using the same language as the rest of the system.
5. Guix home (the home manager) is built in and very easy to use if you already got the hang of Guile Scheme.
6. Guix uses linux-libre, which is fully free kernel. If your hardware is not supported (likely) there is a nonguix channel to get proprietary packages to make it work.
7. The standard guix repository contains only free software. Proprietary software can be installed via some other channels, but not recommended.

And the even more glorious, guix
