It's a little bit different but Astroid is great and my favorite GUI desktop client right now. Lightweight, flexible and renders html all right. It uses notmuch, which takes a little bit of setup but in return you get really good search which I never felt a need to tune. You should also try out if either thunderbird, evolution or kmail does it for you.
If you're up for terminal, aerc (optionally supports notmuch).
roundcube for self-hosted webmail. cypht could also be worth checking out. maybe later on mailpile when/if they get their 2.0 out.
I wouldn't be that absolute about it, but nothing comes to mind as missing or broken from the top of my head so far. That being said, it does look like it would benefit from some more support: https://github.com/astroidmail/astroid/issues/669
