I have had a lot of problems getting the real IP of the client with nginx as a mail proxy, this is my configuration

worker_processes auto;
events {
worker_connections 1024;
}

mail {
server_name mail.example.com;

# Autenticación externa vía HTTP
auth_http http://127.0.0.1:80/mail/auth.php;
proxy on;
proxy_pass_error_message on;

# SMTP
server {
    listen 587 proxy_protocol;
    protocol smtp;
    timeout 300s;
    smtp_auth login plain;
}

# IMAP
server {
    listen 143 proxy_protocol;
    protocol imap;
    timeout 300s;
}

# POP3 
server {
    listen 110 proxy_protocol;
    protocol pop3;
    timeout 300s;
}

}

Does anyone know how I could get it?

Hello zomebodi, Thank you for the question. Could you add a bit more detailed context around what you are trying to achieve as well as a detailed idea of your ideal outcome for that goal would be good too.

An example would be “I am trying to programmatically access the DHCP or Fixed IP address of a client machine so I can build a running list of active clients” or something like that.

This will be helpful in understanding your goal so I can ensure I give you useful guidance.

Heya! Looking at this, I think you might be missing the set_real_ip_from directive in your config. I stumbled upon this Stack Overflow question that seems to cover this exact use case and that was one of the suggestions that helped the original poster :slightly_frowning_face:
