I imagine that this post is more suitable to a Zimbra forum, but maybe the good friends of TurnkeyLinux can help us :-)

On our company (a typical SMB) we use pop3 - smtp emails, and each employee download the emails using MS Outlook directly from the mail service provider.

We would like to us a Zimbra Appliance to be an intermediate email server, so all the emails could be automatically downloaded by the Zimbra appliance, and our employees download the emails from the Zimbra appliance.

The idea is to leave a copy of the company emails on the Zimbra appliance, and that the employees can have also their local copy on Outlook.

We have an ADSL internet connection with fixed IP.

The Zimbra appliance could be installed on the DMZ, and the employees would connect to the appliance from the LAN.

Is it possible to do this? thank you very much.
