High avaliabilty for IMAP/PROXY

- Sorry if it seems to be a little off-topic -

We have deployed Cyrus Aggregator and currently we provide load
balancing and high availability for the Cyrus Front Ends through DNS.
With this scenario, if a Frontend is unavailable it will receive
connections unless we remove it from the DNS record for the IMAP

Does anyone have any better ideas to improve the high availability? I
was wondering about using HAPROXY vs NGINX but I do not know their
behaviours in cases like I mentioned above.

My best regards,
