Hi Adi

in general people want to get the original ip not the proxied ip. The
proxying of the original ip is done by a different method for imap and pop3

However, unless I'm reading this wrongly, both methods are affected by
trusted_networks settings. I guess for people to help further, you'd
need to give more info your configuration settings.
