I was thinking along the same lines but I didn't want to delve deeper until I saw your daily.out log. The thought behind this is that if your daily.out contains some of the other logs like kernel.log it is either being written to by the associated components, and they get where to write by syslog.conf configuration file, or it is being copied in by one of the periodic daily scripts. The above syslog.conf looks ok. So what's left to look at is the periodic daily scripts.
So the key files involved with periodic daily are the following.
/etc/defaults/periodic.conf this is the config file for period
/user/sbin/periodic this is the periodic script itself
And the directory to look at is:
/private/etc/periodic/daily directory of peioric daily scripts
So it would be nice to see the two scripts, the listing of the files in the daily directory, and the listing of the first script in the daily directory (which I would expect to be 100.clean-logs).
I'm posting this without telling you how to do this because I need to come up with a small set of terminal commands and just consturcting this post is taking long enough. This silly forum software has time limits on how long you can do things and I don't want to loose what I've typed so far. I do it in a separate post.
Update:
I downloaded your daily.out. After looking at that, and before worrying about all the stuff I mentioned above, please post just the listing of the files in /private/etc/periodic/daily and the contents of just first file in that directory.
Below is the top portion of your daily.out so that others who can't do the download can see it. This looks like it's comming from an old script. Not the Snow Leopard version. Titles are slightly different and it's doing the log rotations from here.
