I've done some tests today, and included results below: localhost:$ telnet 127.0.0.1 25 localhost:$ nslookup localhost [snip] Name: localhost.localhost Address: 127.0.0.1 localhost:$ telnet localhost 25 Trying ::1... [hangs, would like to know why] somehost:$ telnet mydomain.net <- verified that it points to my localhost, can ping> Trying 194.109.196.149... telnet: Unable to connect to remote host: Connection refused [following ran while somehost tried to telnet to localhost:25] $ tcpdump -i tun0 not port ssh and not port http and not port netbios-ns tcpdump: listening on tun0 15:28:18.608355 somehost.58253 > localhost.smtp: S 3945481990:3945481990(0) win 8192 (DF) [tos 0x10] 15:28:18.608526 localhost.smtp > somehost.58253: R 0:0(0) ack 3945481991 win 0 localhost:$ tail /var/log/maillog [nothing] I am totally clueless as to what part of my system acknowledges or refuses network requests, in general..
