Export Exchange recipients to Postfix server

When you have an Exchange server in your organization and you also use a Postfix server as gateway, you need the list of all valid recipients of your organization at your gateway. In this way, you can reject invalid emails at the gateway, and what’s more important, when the sender address is forged, you don’t spam innocent people with undeliverable emails.

I use this script in Exchange 2003 to generate all addresses.
