Cannot get postfix to listen on wifi interface (en1) I have a Mac running 10.8.4 which I am using as a server which is only connected to my network via Wifi (en1), however I cannot get the stock postfix process to listen on en1.  I have tried a variety of inet_interfaces settings, for example the default setting of all, gives:

# netstat -an | fgrep .25
tcp6       0      0  ::1.25                 *.*                    LISTEN
tcp4       0      0  127.0.0.1.25           *.*                    LISTEN


I have also tried:

inet_interfaces = 192.168.1.100, 127.0.0.1
inet_interfaces = 192.168.1.0, 127.0.0.1
inet_interfaces = $myhostname


But I can see no listen on en1.  Can anyone advise?  Should I ditch the stock postfix and use the Macports one?

(note that I have unloaded and loaded postfix using launchctl between config changes).
OK, long-story-short, there was an additional inet_interfaces line right at the bottom of the file, which has the setting loopback_only.  I can only assume it was written there by some automated tool incapable of properly parsing and recreating the config file.
