I noticed something today that I've known for a while, but didn't really think too much of..

I was looking through the cron jobs of my freshly installed Zimbra server and noticed that there's cron jobs in the Zimbra cron for Dspam. Dspam hasn't been enabled by default in Zimbra in some time.. Is this just an oversight that they're enabled by default? I guess they're not hurting anything, but it's kinda weird that they are left enabled. Anyone have some insight on why that would be?
