With Akonadi + KMail 16.04 this doesn´t work at all with local folders, with 
MBOX folders or with IMAP folders:

What ever I set there, when I open the dialog again, the old settings are 
still there.

Does this work for anyone else with a *newer* version of Akonadi and KMail, 
preferable 17.04 or at least 16.12?

I think it worked once, cause I have non standard settings on local maildir 
folders, but right now changing anything in KMail just does *nothing*. Same 
goes for Akonadiconsole.

So does this work for anyone?


I hope to get newer packages with Debian Unstable soon, but Debian Qt/KDE work 
is currently working on upgrading Qt from 4.7.x to Qt 4.9.1 and providing a Qt 
WebEngine package alongside. (Qt Webengine has been a major pain for the team, 
the resources it needs to build appear to be ridiculous.). There are recent KF 
5 packages already and those Qt 4.9.1 package, but all first needs to be tested 
and then Plasma and Applications.

I may try out KDE Neon Docker container.

Thanks,
