I think RR DNS is the only viable solution under these circumstances. If you can cope with the fact that failovers won't be seamless, I don't think there's anything wrong with that though.

With this proxy setup you describe, what would happen if HAProxy or Dovecot Proxy were to fail?
I think there is no problem with many moving parts, as long as there is a backup plan in case something goes awry. My goal is slightly different, as I want to have HA available across datacenters without using BGP or having control over the IP space (so, no anycast). Just a simple way to get the clients redirected to the other Dovecot server when I lose an entire datacenter network for whatever reason.
you dont need DNS RR for that. just plain DNS entries with a very short TTL.
