Hello,

 

In Exchange, you will need to configure Send/Receive connectors based on the flow of traffic that you require. As an example, a Receive connector to accept mail being sent in from external > ESA > Exchange, and a send connector for outbound traffic going from Exchange > ESA > External. 

 

For HA, it would depend on what you're referring to. The ESAs do not have any form of HA functionality builtin; however, you can configure them into a cluster to share configuration across devices. More information on that can be found here

 

For actual high availability as far as mail traffic is concerned, you will want to configure DNS round-robin and/or have some form of load balancer in place within your network. Then, traffic can move between ESAs automatically if for some reason one is unreachable. 

 

Thanks!

-Dennis M.

You're amazing!

Find below a question from @Doug Maxfield :

vESA on AWS

Good Morning,

We are looking at moving/building new a vESA in AWS.  Just checking to see if anyone has done this.  Any information would help.  I would think it would be similar to "standing up" in a VM environment.

TIA,

Doug
