I think you can do it with a hosted solution- you just need to be able to:
- know exactly what type of hosted solution you have, i.e. RH 4 or 5, Fedora what- ZCS has some very explicit requirements. If some are missing, you may not be able to install them depending on your solution
- you need to be able to direct your mail via MX records to the hosting solution
Overall, you probably want to do it on your own server- you just have much more control that way. If this is for fun, you could try it on a hosted provider and see if you can get it to work.
If this is for profit then don't waste your time or the companies time- get a proper Internet connection and a server. A proper 64 bit Dell or Sun will set you back only about 5 or 6K, with RH licenses.
Also- consider that if you do it on a hosted provider, they have all your email. What happens if they go out of business?
Lastly, I think there are plenty of 3rd party 'hosted' zimbra solutions already out there- just call them up and get out your credit card. |
