I am planing to add eFa as an email gateway for my servers. I have only one domain but several internal email server for failover.
I have found that I should specify the domain and the back end mail servers in the transport file as below so that when the first mail server fails email message will go to second mail server:

mydomainabc smtp:[192.168.2.100]
mydomainabc smtp:[192.168.2.101]

Am I correct?

Not sure, I'd like to know this aswell. Otherwise will need to look at load balancer in the middle

Any thoughts guys?

I don't know how EFA will behave.

Easiest thing to do would be to test it.

Stop the service on the first mailserver - does EFA error out? Does it try the second in the list? I honestly don't know what it would do.

That said, if I were setting up a HA back end for my mail service, I'd have two mail servers with an HA proxy running off a virtual IP - that way, either machine could service the requests from a single transport entry.
