I usually use proxy_pass to cluster of auth backends in the same 
nginx as mail proxy, i.e. something like

mail {
    auth_http 127.0.0.1/auth;
    ...
}

http {
    upstream auth_backends {
        server ...
        server ...
    }

    server {
        listen 127.0.0.1:80;

        location = /auth {
            proxy_pass http://auth_backends;
        }
    }
}
