I want a simple system especially for managing a lot of clients in a LAN, it works in schools and is administrated by teachers who don't want to first study man pages etc before changing such stuff like the IP address belonging to a MAC address, p.e. > How many computers are in your network? More than 200 machines which are owned by the school, and (presumably) a lot more than 200 private machines, like smartphones. > What is the error from thunderbird? Is it an "IP"-error or an DNS- > error? I have to ask the colleague who tries to run the system, may need some time (that is a job which shouldn't disturb "normal" working ...) > How is your routing table? What stands in /etc/resolv.conf? Mailing with Thunderbird works with the lines interface=lo interface=eth0 interface=eth1 The routing table and the contents of "/etc/resolv.conf" are not changed for the case "without any interface line" or "with only some interface lines"; I may not believe that changing the "interface=" lines in the dnsmasq configuration is related to the contents of these files. Viele Gruesse!
