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.

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 ?
