Remote IP address in dovecot

Hello,

I am using a webmail, SOGo, to access Dovecot mail server in IMAP.

SOGo correctly logs the remote IP address, using the standard nginx headers, especially X-Forwarded-For.

However, when I check the IMAP logs, I see my server's IP address for the "remote_ip" value.

I think there is a way to override this value from the environment, but I could not find it.

Thanks for your help,
