New installation of Tumbleweed (snapshot 20170320), home directory imported
from old disk.
I have a mailing list that is shown properly in Contact, but sending to the
list fails with

Fehler beim �bertragen der Nachricht. Message sending failed since the
following recipients were rejected by the server: BdK@t520.internal (The
server responded: Requested action not taken: mailbox unavailable invalid DNS
MX or A/AAAA resource record)

Looking at
https://userbase.kde.org/Akonadi#KAddressBook
I should see a prograum under KDE system settings -> Personal information
This is missing

I can see as well that akonadi-runtime is not installed by default - is it
still required?
Following akonadi packages are installed (by default):
