I don't believe there is anything inherent in Dovecot to do this but if you
have your own backend system health checks you can configure the sql DB to
update which server to proxy a request to based on the results of your
health checks. This would mostly be outside the scope of Dovecot though.

Subject: [Dovecot] pop-proxy to redundant servers ?
I'm considering putting two servers with failover IP-addresses in
front of our pop/imap cluster, with dovecot in proxy-mode running
on both servers. But, can dovecot handle more than one backend
server for each user ?
I.e. I would want to point the dovecot proxy to send userX to
backend-server1, or backend-server2 if backend-server1 is down. Is
something like that possible ?
