By default, exim only allows relaying by the local host, authenticated clients and clients that are listed in relay_from_hosts (which gets filled from the dc_relay_nets setting in debian's config management.) So to allow only authenticated clients, simply don't add any hosts. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
