Hi Martin, Hi Bernhard, I removed all entries with the string "kolab" from files in /etc, downloaded the sources again and proceeded as in the description and it worked. I don't know why it didn't worn before. Even the amavisd error didn't reoccur. This time though I had the old syslog installed, not the syslog-ng. BTW, my system is Debian Sarge. Regards, Markus
