Hello all,


Currently we do load balancing for NGINX server that included in Zimbra as Proxy services with HAPROXY.


but as we see in nginx's log access file all incoming source IP was logged as HaProxy's IP,

the question in how we configure nginx to show client's origin IP instead of HaProx's for IMAP and POP3 (mail) ?

Note: there is solution using Proxy Protocol (https://www.nginx.com/resources/admin-guide/proxy-protocol/) but it's available for http and stream only.
