postscreen is designed to talk to the client directly. Or at least
through transparent TCP proxies. In the proxy case you need to use the
proxy protocol to provide client information. However nginx is not a
TCP proxy, so not suitable for this kind of use.
You could use XCLIENT for connections to smtpd without postscreen.

Please explain which problem you are trying to solve by using nginx.
