Explanation
You can configure a hardware load balancing solution to distribute non-Exchange messages among your Hub Transport or Edge Transport servers [load balancing solution to handle message traffic between the Exchange servers in your organization isn't supported]. If you plan on placing a load balancing solution in front of your Hub Transport servers, you should create a separate Receive connector for that purpose and make sure that only traffic processed by that particular connector is subject to load balancing. This can be achieved by adding an additional IP address to the Hub Transport server and associating this IP address with the new Receive connector. In addition, the Exchange Server authentication option should be disabled on the Receive connector to ensure Exchange traffic doesn't route over it. The following figure shows a configuration where a load balancer is used to distribute messages received from POP3 or IMAP4 clients and non- Exchange SMTP servers among two Hub Transport servers.
