Hi. I have a default installation of Exim with only a few changed settings. It appears to only bind to the loopback interface. I have not set any local_interfaces values, as the default behaviour is to bind on all interfaces. But alas, exim does not respond on its IP address: [root at obiwan ~]# /etc/init.d/exim restart Shutting down exim: [ OK ] Starting exim: [ OK ] [root at obiwan ~]# ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:07:E9:26:FD:29 inet addr:192.168.0.101 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::207:e9ff:fe26:fd29/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:49916 errors:0 dropped:0 overruns:0 frame:0 TX packets:27221 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7366849 (7.0 MiB) TX bytes:3741826 (3.5 MiB) Base address:0xddc0 Memory:fe9e0000-fea00000 [root at obiwan ~]# telnet 192.168.0.101 25 Trying 192.168.0.101... telnet: connect to address 192.168.0.101: Connection refused telnet: Unable to connect to remote host: Connection refused [root at obiwan ~]# telnet 127.0.0.1 25 Trying 127.0.0.1...

Any clues? Thanks. Morten
