hi,

i’ve setup pop3/imap4 proxy using nginx recently, everything work great,  
unless i cannot obtain client ip address, i’m using external auth\_http  
server run on apache/php.

How do i forward client ip from nginx to apache auth server? something  
like ‘X-Forwarded-For’ in http reverse proxy.  
this is what i have done so far by adding auth\_http\_header

mail {  
…  
…

```
   server {
         protocol pop3;
         listen 110;
         starttls on;
         auth_http_header X-Auth-Client-IP $remote_addr;
   }

```

}

i still seeing nginx ip address in apache log  
i need some enlightenment here

TIA
