Re: Anycast provider for SMTP?

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#routing-policy-geo

The other step would be to setup HA in each SMTP node (US and France) such
as LB or Failover. Just an idea.
