Have you ever considered running a local (home) Imap server from which you feed your local clients
(Desktop, Phones, Tablets) ?
I think that is the best option for those who don't like to have their mails on a remote Server.
Years ago, I investigated on that and wrote a summary on how to do this:

- I know this is a bit outdated nowadays (who does still know what swendeleter is ?) but still true and functional for the most parts.

I can second that - everyone should appreciate the years of work that have gone into akonadi*,
nowadays mainly done by Dan Vratil.
And as it is such a giant project, it is no wonder that not all issues can be solved by (mostly) a single developer.
But I also think, akonadi is too complicated by design, and I doubt it would have been made like it is once again
with the experience of the last years...

Just do it - I can recommend giving it a try ...
