I wanted to give back to the community. I have setup a zimbra FOSS server. If anyone is interested, I would be more than happy to host small domains (5-10 users/per domain) with about 50 MB per user. This way ppl can get started with zimbra with no initial cost or upfront fees to see how well it works out for them.
If anyone is interested in this, you can send me an email at firstname.lastname@example.org
