I am also under the impression that this warning should be muted, at least when $ grep interfaces /etc/exim4/update-exim4.conf.conf dc_local_interfaces='127.0.0.1 ; ::1' The rationale is: if my exim only listens to the loopback interface, then I don't need a server certificate, since my exim won't accept connections from remote clients.
