sieve VS Roundcube

FYI You shouldn't really be using procmail for sorting see the notice at the top of this page. Dovecot has built in seive functionality witch you can use this desktop GUI to manage.

use mailsieve scripts, they are amazing. Checkout sieve originally just a thunderbird addon but you can install it as a desktop app, hosted web application or build your own docker container.

Auto Sort into your Junk folder using email sieve (I use this handy desktop app for easily editing) :

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 I'd like to use a Google Addressbook within such app, for example (there is a completely outdated plug-in for RoundCube).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.
