[Cialug] Cannot retrieve mail through internal nework

[Dave Weis]

edit /etc/postfix/main.cf and look for this section:
inet_interfaces = all
#inet_interfaces = $myhostname
#inet_interfaces = $myhostname, localhost
#inet_interfaces = localhost
Make it look like this, restart postfix. It only listens locally by 
default for security.
