I use to receive a dianiostic email as follow
Date, obviously, change day by dayCode:
from: "Cron Daemon" <firstname.lastname@example.org>
subject: Cron <zimbra@ghelis> /opt/zimbra/libexec/zmdailyreport -m
message: bzip2: /var/log/zimbra.log-20100828.gz is not a bzip2 file.
I have just update to 6.0.8 with no problem but this happened also with 6.0.7
What can cause this annoying message?
