Hello,

we have configured nginx to work as mail proxy for backend dovecot servers. Dovecot servers behind nginx proxy are showing internal nginx ip address for every client when running 'doveadm who' instead of showing real client IP addresses.

Is is possible to configure this setup to show real client IP addresses when running 'doveadm who' on internal dovecot servers or to configure nginx to show which user-ip pairs are proxied to which servers?
