Setting up test server

[Lance Haig]

Hi,

How do I copy every email that has been cleaned to another server?

I am testing the new bongo mail server and I was wondering if I could 
tweak postfix somehow to copy all mail to this test server.

Can someone point me in the right direction please. I am not sure what 
to google for so I thought I would ask

I am running postfix on Fedora 4 with MS

Thanks

Lance
