I use this system as an inbound email relay on, or outside, the

configure the firewall to only allow my outside email relay to send
traffic to the Exchange server.
In order to avoid accepting email for users I don't have I've got a

Subject: Configuring SA as frontend to Exchange
Have been running SA on CentOS for a few years now and everything has
working great. But the powers that be want to move to Exchange so I am
to plan a SA frontend that feeds the Exchange server.
As I was thinking over how SA works now and how it might work in the my

anymore like it is now. Or would I be limited to just having SA
Also, if anyone has some good links to setting up a SA frontend to
