Problems after reconfigure MTA - iMSCP not accessible

  • Hi at all,

    because a attempt to reconfigure the MTA to dovecot in iMSCP imscp-1.5.3-2018120800 on Debian 8.11 I 've tried to reconfigure the whole system - but nothing goes right...

    Error-Message as following:

    1. [ERROR] iMSCP::Stepper::_callback: Couldn't remove the `/var/spool/postfix/var/run/courier/authdaemon' directory: problem unlinking /var/spool/postfix/var/run/courier/authdaemon: cannot remove directory: Das Gerät oder die Ressource ist belegt

    and nothing in imscp is running

    I have no Idea, where I can search to fix the error... or in which logfile more informations about that...
    Any help and advice is welcome
