As I won't be able to run Zimbra on my server (because of OpenDirectory that I need to keep running), I would like to uninstall Zimbra.

So far, I found out that I need to remove everything in:
- /opt/zimbra
- /Library/Receipts/zimbra-*

Unfortunately postfix do not run anymore now. I tried with a reboot too.
I found a post on the forum explaining some iptables stuff, but Mac OS X does not use iptables... So I can't apply the "hack".

I'm really anxious wondering how to solve this issue as this server is hosting lots a virtual domains and I need to recover asap.

Any hint?

Thanks in advance.
