I use SMTP, and since proxy hide real IP address, many security features of mail server, based on sender IP, become useless.

Dear Experts,<br />
<br />
I just created the proxy, based on TIdTCPMapping Indy component, and I have a huge problem - the destination server can't see the original client IP. For example, user from 11.11.11.11 connects to my proxy at port 2525 then proxy redirects request to server at port 25, but server always see host IP where proxy is running (in my case 127.0.0.1), so real IP 11.11.11.11 is hidden! How can I get rid of this proxy &quot;feature&quot;? I know there can be low-level NDIS, LSP and TDI stuff, but I'm not C++ programmer.<br />
<br />
TIA,<br />

How can I get rid of this proxy "feature"? I know there can be low-level NDIS, LSP and TDI stuff, but I'm not C++ programmer.
