neutron VS Roundcube

PS: I hope that we selfhosters will have a modern, efficient, easy to use mail suite one day with modern features like JMAP, good self-learning spam integration, automated checks and validations for SPF/DMARC/DKIM or whether the IP/host suddenly appears in a blocklist and integrated encryption at rest for emails. Something that isn't 30 services in a container image, with 30 different configuration styles. Maybe even with an API integrated that's compatible to the ProtonMail frontend (like the neutron server once intended to be). Anyway, I'm sorry for dreaming. ;)

A bit related: there was a FOSS backend once but I don't think anyone wants to push further.

Some folks once started neutron which is an email server that can be used with the FOSS Protonmail web client but it was abandoned. And I guess you'd want to support JMAP in addition to IMAP as well apart from having automated encryption of incoming plain-text emails.

Anyway, to the topic: there was once neutron which is a server that aimed at ProtonMail compatibility. So that'd would simply would be able to use the same open source frontend from ProtonMail. However, this was abandoned. So you, or somebody else, could revive it.

Some folks also started implementing an FOSS ProtonMail but this project was abandoned at some point. But maybe someone will fork and revive it one day.

Two devs once started implementing a free ProtonMail server but they abandoned it. It's understandable, since it's a lot of work.

Some folks once started a free implementation of the Protonmail backend in Go. Maybe you want to revive it?

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.

The GitHub issue talking about this [1] is such a mess too. Maintainers closing the question with a vague non-answer, deleting comments left and right, etc. Sounds like someone stole the money and everyone is either complicit or too embarrassed to admit that it happened.

https://github.com/roundcube/roundcubemail/blob/master/SQL/mysql.initial.sql Take a look at the tables an you get a idea, session for the app, users-table, contacts-table, dictionary, etc.

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.

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.

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

Roundcube might fit the bill for you.

I'd do it with a local IMAP server in conjunction with a webmail client that connects to it. Dovecot is a fantastic and easy to use IMAP server. Webmail clients are a pretty personal thing, but the last time I used Roundcube it seemed pretty good.
