Same answer as last time this was asked, I am very happy with Posteo.
Sorry for the delay, but the answer was long enough that I turned it into a blog post instead. Feel free to try it out.
Gnus in Emacs, configured to use autocrypt.
Posteo. Happy with them. For client, gnus in Emacs. Have it configured to do Autocrypt too, but almost nobody else on the planet does 🙁
Same as in the other thread, I’m going to recommend fossil-scm.org
Works for me.
