A server exports /var/spool/mail via NFS and acts as a "smarthost" for the satellites to relay their messages to outside. Everything works except for relaying. Server refuses to relay with the message: 550 relaying to <whatever address> prohibited by aministrator How should I setup /etc/exim.conf to enable relaying from the satellites (and only from satellites or at least only from within local domain) to anywhere. Thanks, Sergey.
