Configuring nginx as mail proxy

[Laurent Bonetto]

Thanks. That was indeed my first issue. I did sudo port edit nginx, added --with-mail to the config options, reinstalled, and now I am passed that error.

I then got an error that no events was present so I just added 
 events {
 worker_connections 1;
 }

Now nginx is starting but I never see any hit to my mock service despite it being specified in auth_http
    auth_http    http://localhost:8080/authorize;
No errors reported in the error log.

When is nginx expected to hit the url specified in nginx? When it gets launched? When an event occurs on the ports 110 and 2525 with the protocols I specified?

I tried sending emails to/from my mail server that uses POP3 on port 110 and SMTP on port 2525 and never saw any hit to the authorize url. Am I missing another component in my config?

Again, here is my current config:

   worker_processes  1;

  error_log  /var/log/nginx/error.log info;

 events {
 worker_connections 1;
 }

  mail {      
    server_name       <my mail server>; 
    auth_http    http://localhost:8080/authorize;

    pop3_auth         plain apop cram-md5;
    pop3_capabilities "LAST" "TOP" "USER" "PIPELINING" "UIDL";

    smtp_auth         login plain cram-md5;
    smtp_capabilities "SIZE 10485760" ENHANCEDSTATUSCODES 8BITMIME DSN;
 
   xclient           off;

    server {
	# SMTP on port 2525 not 25
        listen   2525;
        protocol smtp;
    }
    server {
          listen     110;
          protocol   pop3;
#          proxy      on;
          proxy_pass_error_message  on;
    }
 }
