IronPort ESA - HA and Dual Homing

Hello, i have a customer that want to do HA and Dual Homing implementation. I want to ask what is the best way to implement HA for IronPort ESA? As i know the cluster configuration only used so the policy can be distributed equally. And what about dual-homing scenario? Is it supported with IronPort, and how do it works ?

Regards

What exactly do you mean by multi-homing? Ironport email appliances support configuration of multiple interfaces (physical or vlan) , to which you can then attach Listeners (SMTP processes). You could thus configure your servers to receive or send email on multiple IP addresses, depending on your network config.
