where would two A records and it would round rob, so send to both.

or use load balancer for sending to and if the first is not available, do not think this logic is available in postfix.

What thewomble says. RRDNS or a single ip served by a load balancer.

If you’re really paranoid, you can have multiple, load balanced ips from multiple load balancers, but the I’ve never had a use case for this with email.

What exactly is the problem you are trying to solve/avoid?
