Just a question here. im setting up kopano 8.6.80, im very happy with these new packages, its a bit more looking here my logs went.

i notice the following for kopano-search.

systemctl status kopano-search
● kopano-search.service - Kopano Core Search Engine
   Loaded: loaded (/lib/systemd/system/kopano-search.service; enabled; vendor preset: enabled)

May 08 09:49:36 mail1 systemd[1]: kopano-search.service: Failed with result 'exit-code'.
May 08 09:49:36 mail1 systemd[1]: Started Kopano Core Search Engine.

This is a contradiction.
Kopano search started successfully but kopano-search.service: Failed with result ‘exit-code’.
It runs fine, no problems seen sofar, imo small bug in the exit-code.
