[olug] Prying open port 25

If it's running postfix, some distributions tell it to only listen on 
loopback. If telnet localhost 25 shows signs of life, edit 
/etc/postfix/main.cf and look for inet_interfaces:
inet_interfaces = all
#inet_interfaces = $myhostname
#inet_interfaces = $myhostname, localhost
#inet_interfaces = localhost

The last line is what you probably have, the first line is what you need.
