how to configure frontend/backend servers tofor mail delivery
Posted on 2008-10-12
I need to properly configure mail flow between frontend and backend servers in exchange 2003. The topology will be:
2 frontend servers behind the perimeter firewall
2 backend servers clustered behind the perimeter firewall.
There will be a smtp gateway/spam/virus filtering appliance to send outbound mail through.
Should the frontend and backend servers be configured as bridgehead servers on the opposite sides of a routing group? The frontend and backend servers will all be on the same subnet. Should a smpt connectors on the backend servers be configured as smarthosts pointing to the smtp gateway?
What about inbound mail flow from the internet?
What would be a recommended configuration?
