Real IP in header for SMTP Nginx Mail Proxy

[coolmike]

Hi

Thanks a lot for your answer. This sounds great, but when I enable it, I
just get the following at my exim mailserver log:

2017-01-20 13:42:00 SMTP connection from [46.xx.xx.xx]:54087 (TCP/IP
connection count = 1)
2017-01-20 13:42:00 SMTP connection from (mailproxy.xxxx.com)
[46.xxx.xx.xx]:54087 lost

I don't know why the connection is lost when I enable xclient. 

Do I need a special configuration for my exim mailserver when I use
xclient?

Regards
Michael
