I am trying to use smtp connection for an email marketing software and  
would like to use smtp or pop3, but I am not sure where to start. I have  
mailauth.pm in /root/auth/ but I am not sure if that is write. If the  
previous is correct, is this also correct in nginx.conf:

mail { auth\_http 127.0.0.1:80/auth; pop3\_capabilities “TOP” “USER”;  
smtp\_auth plain login; server { listen 110; protocol pop3; proxy on; }  
}

If none of the above is correct, can you point me in the write direction  
or documentation on how to accomplish this? Thanks.

nginx can not work as SMTP or POP3 server, it can only proxy connections  
to real mail servers.
