Hi,

I have exchange 2007 hub server witch internal ip and another pc edge server witch public ip;

how should I configure xeams?

I assume the one on the edge have two network cards: external and internal, right? If this is true, you should be able to use the SMTP Proxy server to receive in-bound emails. Just specify the LAN IP of Exchange 2007 for the "Actual Email Server" field. 

ok, i used use the SMTP Proxy server to receive in-bound emails in the external card, but in "Actual Email Server" the lan ip of Exchange 2007 i put hub server or edge server, and I have to disable antispam in the edge server of Exchange 2007?

Thanks

What is the purpose of your Edge Server? If all it is doing is filtering, you can replace that with Xeams and put your Hub server in the "Actual Email Server". If the Edge Server is doing something else besides filtering, use the "Edge Server" in Actual Email Server" field and disable filtering on Edge.

Ok, my current exchange server edge is only a filter, then the I disable. Xeams can work together with the exchange filter?
