The /etc/mail/relay-domains file for restricting hosts from being able to send mail via our relay host, is not actually restricting anything. Hosts that are not in it/not in the allowed domains as well are able to send mail through the relay host regardless. Host restriction only works via the /etc/hosts.allow file and TCP Wrappers. How does the local-host-names file work, and does it relate to relay-domains?
