Brightmail Messaging Gateway and Exchange 2010 Receive Connector
I'm currently cleaning up the setup of our Brightmail/Exchange 2010 environment that was configured improperly by a previous tech.
We have two Brightmail gateways and three Exchange 2010 CAS servers.
This question is in regards to the Exchange 2010 receive connector for all our CAS servers.
Currently the receive connector has 0.0.0.0-255.255.255.255 (everything) for the remote server IP address with Anonymous, Exchange users, Exchange servers, Legacy Exchange servers
If I'm receiving mail from only the Brightmail gateways would I create a custom receive connector that uses the anonymous permission group and has the addresses of the two gateways? Am I correct with my setting change? Is there anything specific that should be set in the Authentication tab?
