    Default Using Zimbra Behind Nginx

    I run a small SOHO network. I NAT/port forward on my router to get traffic to my handful of servers.

    I setup an Ubuntu 10.04.4 server with Zimbra 7.1.4_GA_2555.FOSS. Let's call it host1.internal.local.

    The server currently has two mail domains, call them and Both offer webmail access at and

    I have a separate server with nginx. I want to configure nginx to reverse proxy to the Zimbra server, such that I can direct all HTTP/HTTPS to the nginx server and then distribute across other servers from nginx. I need to send webmail traffic via matched host address/headers to the Zimbra server.

    The basic configuration of:

    server {
    listen 80;

    access_log /var/log/nginx/access.log main buffer=32k;
    error_log /var/log/nginx/error.log;

    location / {
    proxy_set_header Host $http_host;

    does not seem to work. (LAN DNS would resolve the to the right server.) I get a 500 error. (The same config proxies regular www sites just fine.)

    Has anyone ever done anything like this? If so, how?

    i don't no if this will help but i have set up nginx in front of zimbra for https ( commercial certificate ) in the same machine.

    i have added the conf below in my virtual hosts env.
    Replace with your LAN ip.

    location / {
           proxy_redirect off;
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_connect_timeout 30;
           proxy_read_timeout 120;
           proxy_send_timeout 120;

    Tip : make sure that you have added in your conf :
    client_max_body_size 25m;
    to allow to attach files in your emails & briefcases

    I hope it helps!!
