I have tried several, and liked none of them. I'm currently on Geary, but it's lacking in functionality, and it has things like search results being a bit different upon each of my searches. Starred messages cannot be shown on top. Eyeroll. I think Evolution and Thunderbird are the top contenders, and of the self-hosted ones, Roundcube. https://wiki.gnome.org/Apps/Geary https://roundcube.net/. - Source: Hacker News / 3 months ago
You could try a standalone email client like Mozilla's Thunderbird, or if you're experienced running a web server, you could check out something like Roundcube. I suppose you could even run it locally if you're familiar with PHP and/or Docker. Source: about 1 year ago
What I really miss is a "web companion" for Thunderbird, basically something like https://roundcube.net/ or https://www.horde.org/apps/webmail, but a bit more powerful and with better UX. I'd like to use a Google Addressbook within such app, for example (there is a completely outdated plug-in for RoundCube). Another important thing would be powerful and fast search. - Source: Hacker News / over 1 year ago
Alternatively if you want to keep what you have I wouldn't recommend using the SoGO even though it's the nicest and most modern option. Mainly because it's a full groupware client and will require a lot of configuration. Instead using Roundcube is probably your best option. Source: over 1 year ago
