how to get remote_addr in ngix for POP/IMAP with perl module

[moorthi]

other issue i'm getting is when i login thru php webmail (which connects to
nginx for imap proxy) I am not getting original remote_addr in nginx server,
instead i am getting 127.0.0.1, I've tried below header in php webmail where
imap login happens, using
header('X-Forwarded-For: '.$_SERVER['REMOTE_ADDR']);

how should i get original remote address in nginx.
