    Webmail: Many people don't even use an e-mail client today -- they use webmail to access their messages, or they use a local app that itself depends heavily on a webmail server on the backend to do the heavy lifting. When the server is doing the e-mail handling and rendering work, the server has to have access to the cleartext. Even in situations where the messages are decrypted in javascript (or a Java applet) on the client side, if the client-side code is sent by the server, the server could be compromised and told to send different code (see Hushmail's failures in 2007) How do we fix this? We need more e-mail client developers to take e2ee e-mail seriously, and we need them to focus on security and usability. Browser-extension-based e-mail clients are another possibility (e.g. Mailvelope and its interaction with webmail) systems like Roundcube), but they still rely on a lot of metadata to be exposed on the server-side.

    After further investigation this feature seems to be best implemented on the mail client. There is a feature request / plugin repo that implements this (for the purpose of getting rid of the "mixed content" warning, but it has the same effect that I'm looking for) in the Roundcube mail client back in 2017/2018:
  • Internal email server / service
    4 projects | | 1 Oct 2021
    I have an internal only mail server that doesn't send or receive mail outside my LAN. I use docker-mailserver for this. It's fairly easy to set up a minimal server though I haven't figured out how to enable SSL/TLS so everything is unencrypted in the backend at the moment. I mainly expose the mail server to my other selfhosted services so they can send notification emails to users. Users access their mail through a selfhosted roundcube webmail frontend. No IMAP/SMTP ports are exposed on the LAN or externally. It's enough for my use case (to teach my kids email). The only downside for me is that it doesn't support password changes from the webmail interface natively. All administration tasks are performed using a shell script, including password changes, so only the administrator can change the password for any user. There's a third-party add-on script that enables user password changes from the web client but I haven't investigated/implemented it, so don't know how well it works. It's also possible to set up SSL/TLS encryption for IMAP/SMTP but, in my case, it's less straightforward than described in the documentation because I want to keep it strictly internal only and don't want to open any ports on my router for email. I haven't been motivated enough to poke further because the setup works well otherwise.

    I personally soured on Kolab after the whole roundcubenext debacle. Also I ended up having some serious issues because files are stored in IMAP on Kolab

    Of course not. Most readers would understand by "Postfix/Dovecot" that Postfix is the MTA in the equation, Dovecot is the IMAP server, that something like Roundcube is used for the webmail, and there are likely other pieces depending on the business needs. You know that, too. If you want to argue against a Postfix and Dovecot based stack, then please do so without comparing apples and applesauce.

    That seems pretty unfortunate. For example, I remember Roundcube being pretty neat, but surely it handles enough user data to require COPPA compliance... so now that can't be GPL'd anymore?

    I imagine this comes down to personal preference a lot, but I strongly prefer Roundcube over Gmail. They have improved a lot over the past years, if you have some preconceptions.

    But then I also very much prefer a hierarchical/directory tree approach to organizing e-mail than labels&search as Gmail does it.

    More similar UX-philosophy can be found in Mailpile[1] and Cypht[2]. Both still have decent amount of moving parts but are continuously progressing.
