Neomutt is good but it can be a pain to configure without a script. I
recommend people who want to use Neomutt for the first time use this wizard https://github.com/LukeSmithxyz/mutt-wizard
I justed started using mutt configured using this wizard since I have to use exchage/outlook for work which still has a really buggy web UI. So far it's working a lot better than when I've previously tried to manually set up mutt.
