Forum: NGINX Nginx - SMTP no authentication

Hi friends,

Please help me to configure SMTP without authentication on ngnix. I have
even applied the patch, which is given in this url
http://www.ruby-forum.com/topic/187018#new . I am running postfix in the
same server and ngnix mail is running in the 225, my configuration looks
like this


mail {
#    proxy_pass_error_message  on;
    auth_http  http://127.0.0.1:8080/mail/auth;
    xclient    off;

    server {
        listen     225;
        protocol   smtp;
        smtp_auth  plain;
    }
}

http {
   access_log /var/log/nginx/access.log;

   server
   {
        listen       127.0.0.1:8080;
        server_name  localhost;

        location = /mail/auth {
            add_header Auth-Status OK;
            add_header Auth-Server 127.0.0.1;
            add_header Auth-Port 22;
          return 200;

        }
    }

}

is there anything wrong with my configuration? when i am tring to telnet
to sever to the port 225, i am getting the following

telnet mailserver 225
220 mailserver ESMTP ready
helo
501 5.5.4 Invalid argument
mail from:test@test.com
530 5.7.1 Authentication required


Thanks,

This wasn't a good idea, patch in question isn't needed neither
for version mentioned nor for any up to date.

Though this isn't related to the "problem" you see.

"HELO" command requires an "domain" argument.  See RFC 5321 for
details.

You configured nginx with "smtp_auth plain" and try to send mail
without authentication.  "Authentication required" is expected and
correct reply.

mail
to me, it display "530 5.7.1 Authentication required".
