Mailcow is the best! I use it with Rainloop as Webmail interface because SoGo (preinstalled with mailcow) offers to many features for me. Setup is easy (uses Docker) and it's updated nearly every week.
P.S. If you are looking for affordable European VPS, you may want to check out Contabo.
Edit: Someone mentioned updating was problematic with some mail stacks. Mailcow provides an updater script which does the job for you, works like a charm.
I thought about this as well, but I didn't look into how to integrate a separate existing webapp into Nextcloud. I'm using rainloop as the web client for my email, and this exists as a Nextcloud app as well (when it seems that Nextcloud integration was an afterthought). So maybe this is possible? Once the project matures I hope that others look into it.
Rainloop is a clean, responsive webmail, you can configure it for any mail provider.
CipherMail is another, much more complex solution.
Rainloop - https://www.rainloop.net/ - Self-hosted and open-source and can connect to any IMAP/POP3 provider.
You're normally viewing HTML emails, why load up yet another HTML renderer when your browser does it well anyway?
What about Rainloop? It's basically a carbon copy of gmail https://www.rainloop.net/
Or the semi opensource Hiri or Mailspring Unfortunately you have to setup an online account before using them which is a bit dubious. But they are kinda pretty?
I've heard you can run your own docker instance of the membership sever for Mailspring.
Wenn es dir nur darum geht, mehrere Accounts über eine Webseite zu erreichen: du kannst bei Gmail auch Mails von anderen Accounts abholen (nur über POP) und auch senden.
Roundcube ist schon ganz ordentlich und quasi-Standard was Open Source angeht. Alternativen wären zum Beispiel Horde, Rainloop und Mailpile. Horde ist eine komplette Groundware mit Kalendar und so weiter, lässt sich aber auch auf den Mail-Client runterstrippen. Rainloop war recht umständlich mit mehreren Accounts, als ich es mal getestet habe. Mailpile ist recht vielversprechend und scheint 'ne Ecke weiter zu sein als vor ein paar Monaten als ich auf der Suche nach einer Gmail-Alternative war.
Ich bin bislang aber immer noch beim Gmail - das Benutzerinterface ist für mich einfach unschlagbar.
Zur RPi-Frage kann ich nichts sagen, habe seit dem Model A keins mehr benutzt. Prinzipiell würde ich aber sagen: mehr Ram gewinnt.
I personally use gmail for most things, but lately I've set up my own email server with postfix and dovecot. I used a DigitalOcean VPS and this guide. (test it at ) I use RainLoop Community Edition for webmail.
Spontaneously, I would have recommended Rainloop.

But development seems to have stopped and the issues are piling up. Among them are at least two security vulnerabilities. Because of this, the fork https://snappymail.eu was started. This should be almost identical to Rainloop in terms of functionality.
I don't know too much about Docker. But in the repository there is the file docker-compose.yml.
I've enjoyed it greatly. I love that I can be my own postmaster and make as many mailboxes as I want (assuming I'm not abusing it). Also, if Migadu ever goes under, I could transfer my domain to another service like Mailbox.org. Their webmail client is RainLoop, which you could demo here if you're interested: https://www.rainloop.net/try-now/
They have a free evaluation tier with no time limits, so if you have a domain lying around, I recommend trying it out!
Hrm, that's quite odd then. From here it says this:

Clash of licensing, much?
GSuite still ahem organizes your stuff for you. If you go to Google Payments and Subscriptions, you'll see every flight, hotel, and restaurant reservation that has ever hit your Google account. If you do Google takeout, you'll see all kinds of stuff and location data that you didn't expect to be there. I thought the same about GSuite as you did until I started doing a bit of digging.
In terms of how I've done my webmail, I have webmail.mydomain.com using the software from https://www.rainloop.net/. I have IMAP and SMTP from a regular hosting provider (<$50/yr). I was originally all encrypted and whatnot with Tutanota, but for me that's overkill (and I'd never be able to get my wife to use it). I just want to get rid of the Google surveillance, not hide from the government. So it does the trick for me.
[https://www.rainloop.net/](rainloop) seems really nice, the layout looks a lot similar to protonmail webmail! but as I understand, it just refers to the e-mail client, right? I couldn't find any information about the server, like how secure it is, etc...
