I want to modifiy logrotate for zimbra log files.
I want to integrate date on log files likes this zimbra.log.20120316.tar.gz

there is no consequence for zimbra if i change all zimbra log files rotation ?

It s a proposition but can zimbra integrate this in feature version because in france we must have an legal archiving for receive/send mail and access.
With the date it's more simply and if it's store on one month it's better because we can archive on LTO every month
