I am completely new to nginx and need some help with the configuration.</p><p><strong>Here is what I did:</strong></p><p><strong>First</strong> I built a service that mocks the authentication services described here: <a href="http://wiki.nginx.org/NginxMailCoreModule" rel="nofollow">http://wiki.nginx.org/NginxMailCoreModule</a>. For example, </p>
<pre><code>curl -v -H "Host:auth.server.hostname" -H "Auth-Method:plain" -H "Auth-User:user" -H "Auth-pass:123" -H "Auth-Protocol:imap" -H "Auth-Login-Attempt:1" -H "Client-IP: 192.168.1.1" <a href="http://localhost:8080/authorize">http://localhost:8080/authorize</a>
</code></pre><p>returns the following response header (no matter what Auth-User, Auth-Protocol, and Client-IP are for now):</p><pre>< HTTP/1.1 200 OK
< Content-Type: text/html;charset=ISO-8859-1
< Auth-Status: OK
< Auth-Server: <my mail server here>
< Auth-Port: 110</pre><p><strong>Second</strong> I installed nginx on my mac after installing macports:</p>
<pre><code>$ sudo port -d selfupdate
$ sudo port install nginx
</code></pre><p><strong>Third</strong> I created an nginx.conf with the following:</p>
<pre> worker_processes 1;
error_log /var/log/nginx/error.log info;
mail {
# not needed because returned in Auth-Server actually?
server_name <my mail server here>;
auth_http <a href="http://localhost:8080/authorize">http://localhost:8080/authorize</a>;
pop3_auth plain apop cram-md5;
pop3_capabilities "LAST" "TOP" "USER" "PIPELINING" "UIDL";
xclient off;
server {
listen 110;
protocol pop3;
proxy on;
proxy_pass_error_message on;
}
}</pre><p><strong>Here is what I got running nginx:</strong></p><p>$ nginx -V
nginx version: nginx/1.2.4
configure arguments: --prefix=/opt/local

nginx: [emerg] unknown directive "mail" in /opt/local/etc/nginx/nginx.conf:6</p><p>The only mention of that error on the web brings up a discussion in Russian and the translation is "This question is no longer relevant"</p><p>My questions:</p>
<ol>
<li><p>Why am I getting this unknow directive?</p></li>
<li><p>Does my config look correct at first sight or am I missing some
key component for the mail proxy to work using the authentication
approach described here: <a href="http://wiki.nginx.org/NginxMailCoreModule" rel="nofollow">http://wiki.nginx.org/NginxMailCoreModule</a>?</p><div><br></div><div>Thanks a lot. мерси!</div></li>
