mail module hides client's IP

[Zoltan Borsos]

Hello Everyone,

thanks for accepting my subscription request.

Does anyone have experience how the client's IP address can be 
passed to the imap server when nginx works as imap proxy?

Dovecot and Nginx work on the same server and imap-login entires
in mail.log show 12.0.0.1

Thanks,
Zoltan
