I recently converted my company over to using Zimbra, and so far am very happy with the result. One thing I do need a little help with is getting some redundancy into the system. I have ~30 international users connecting to my server through Indonesia, and ~100 users connecting locally from Vancouver. Since my company is not yet ready to shell out for internet connections with SLAs, I find that at least once a month there are some short system outages.
This wouldn't normally be such a big deal, but since ~30 people are on basically the opposite working schedule as me, it means that any downtime is magnified by the amount of time it takes me to get into the office. What I'd like to do is have the Indonesian users set up their own server (as 'mx2.mycompany.com'), that can act as a secondary access point, and perhaps the primary access point for them (as the 'net connections between Indonesia and North America are generally pretty spotty).
Can someone point me in the right direction for how best to achieve this?
