Toward understanding ZCS better
I'm thinking it would be very beneficial for me to get some training in Zimbra [opensource edition] administration. I'm not talking about having someone walk me through the zimbra admin web interface; I've been a zimbra admin for about 5 years, and have a fairly decent grasp of most tasks and basic setups and configuration.
However there are many things that I really don't know or don't know very well... like what config files can I change - that won't "bite me" later. How does zimbra implement it's spam control, (or even postfix) and what's the correct way to "mess" with them? What configuration options are there that I don't even know about that I haven't needed yet, and therefore haven't searched the forums to know they exist, but could really help me if I knew about them..?
I suspect there are a lot of us who would be interested in something like this...
