Hi, - 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 service. 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, Fabio Soares Schmidt Linux Professional Institute - LPIC-3 Microsoft Certified Technology Specialist: Active Directory ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
