Forum: NGINX IMAP: auth_http

nginx seems to require being pointed to an HTTP server for imap
authentication.  Here's the protocol spec:

http://wiki.nginx.org/MailCoreModule#Authentication

Is the idea to program this server yourself or does a server like this
already exist?

It's usually a script written individualy for a specific system.
Some samples may be found on the wiki, e.g. here:

In that case I request for nginx's imap proxy to function more like
imapproxy which is easier to set up.

The goal of nginx imap proxy is to route client's connections to
different backends, which is very different from what imapproxy
does.  It's more like a perdition.

If you want nginx to just proxy all connections to a predefined
backend server, you may use something like

    location = /mailauth {
        add_header Auth-Status OK;
        add_header Auth-Server 127.0.0.1;
        add_header Auth-Port 8143;
        add_header Auth-Wait 1;
        return 204;
    }

as a dummy auth script.
