    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.
  • Audacity fork without the nasty policy change
    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.
