I could be mistaken, but you might get all of this done with AWS's Route53. I would read this: http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-policy.html... The other step would be to setup HA in each SMTP node (US and France) such as LB or Failover. Just an idea. On Mon, Jun 15, 2015 at 12:50 PM, Joe Hamelin <joe@nethead.com> wrote:
I have a mail system where there are two MX hosts, one in the US and one in Europe. Both have a DNS MX record metric of 10 so a bastardized round-robin takes place. This does not work so well when one site goes down. My solution will be to place a load balancer in a hosting site (virtual, of course) and have it provide HA. But what about HA for the LB? At first glance anycasting would seem to be a great idea but there is a problem of broken sessions when routes change.
Have any of you seen something like this work in the wild?
