Hi to all,
I am fetching mails with get mail and hand them over to kopano-dagent. Processing one users mail works very well, but there problems processing another user. dagent logs:

Fri Sep 28 07:52:46 2018: [31062] [error  ] Command "/usr/sbin/kopano-mr-process" "<user_email_address>" "/etc/kopano/dagent.cfg" "00000000655E95B9CAC044A4987E548AC5B47F780100000005000000EB3F94843C614FC6B0F23A62C57D8E1600000000" exited with non-zero status 1

When I call /usr/sbin/kopano-mr-process from the command line, it says:

File "/usr/sbin/kopano-mr-process", line 4, in <module>
    from kopano_utils import mr_process
ImportError: No module named 'kopano_utils'

though, kopano-utils is installed:

dpkg -l | grep kopano-utils
