Authenticating Against A 3rd Party Mail Service

[gregr]

Hello Everyone,

I am quite new to networking and rules behind domain names and how the communicate.
The question I have is. Can Zimbra be configured to pull mail from a 3rd party hosting service. For example, Bluehost.com is the web and email hosting service for my non-profit.

What I would like to do is have my zimbra server in house. Make Zimbra pull all email down from the hosting company onto zibra and then distribute all mail to the proper mail boxes on zimbra. Rather than have 30 outlook clients connecting to the email isp individualy to get their to mail?

Is that possible? And what direction should I be looking to configure my fedora box to do so, If this is at all possible. I currently have fc4 installed with zimbra running. I can send mail but cannot receive at this time.

Thanks in advance and this truly is an incredible find!

Greg
