In Tiger Server, some typo has been added to the daily scripts, which are located in /etc/periodic/daily/
These scripts are activated by the Server Admin GUI when enabling log rotation on the Mail logs.
The problem here is that the amavisd log is rotated but the amavisd master process is not HUPed, so the amavisd.log file stays empty till this is done… Not very useful.
The problem is located in the 700.daily.server.cyrus file in the /etc/periodic/daily folder.
%logsAndProcesses = ("/var/log/mailaccess.log","syslog",
Yes, read it closely… amivisd… Apple programmer who must have really been tired and fed up with writing config files…
Change the amivisd to amavisd and your problem is solved…
