I'd like to have my mail on my computer, so a local maildir... In the past I've used pine and tried neomutt, while far better than classic Thunderbird/Evolution etc I do not feel much at home with them... I'm at home now with my mix however even if it works really well and far better than any other things I tried it's still too complex for many people and that's not good because we need to attract young people to keep and feed the community instead of having all drooling behind the latest web(cr)app from one of the few supergiants... Sometimes I do some talks about GNU/Linux mostly at my ex university and high school, normally people see a bit astonished and attracted my "dancing screen" with Emacs, they are willing to replicate at least part of my setup, they are willing to learn. But too many simply try and after few time quit in frustration because it's simply too long and complex for them. Of course I know that good things can hardly be "for everyone" but we can provide better defaults. I've tried to give a sanitize personal config, it was a regular failure because few MELPA packages randomly disappear or fail to being properly auto-installed. I end up to give pre-made tarballs with a quick linking script and certainly that's not much a good business card especially if there are more and more few teachers that teach FOSS stuff and more and more books and lecture note that feel NO shame in suggesting proprietary software...
