Modify proxy_smtp_server_ip and proxy_pop3_server_ip to configure the IP address that the IMSS daemon binds to.
  • If proxy_smtp_server_ip is not specified, the SMTP proxy service sets the IP address to 127.0.0.1.
  • If proxy_pop3_server_ip is not specified, the proxy service sets the IP address to 0.0.0.0.
  • If proxy_smtp_server_ip and proxy_pop3_server_ip specified as all, the proxy service receives packets from all interfaces, including IPv4 or IPv6 clients.
  • If proxy_smtp_server_ip and proxy_pop3_server_ip specified as 0.0.0.0, the proxy service receives packets from all interfaces, but is limited to IPv4 clients only.
The following changes configure the daemon to listen to both IPv4 and IPv6 networks:
proxy_smtp_server_ip=all
proxy_pop3_server_ip=all
