[Mailman-Users] new users get welcome e-mails but posts aren'tgoing out

[Rabinowitz, Ari (Exchange)]

Try checking to see if postfix is configured to only listen on the loop-back interface (localhost 127.0.0.1).  You should check the inet_interfaces value in main.cf.  If it says
inet_interfaces = localhost then that is probably your problem.  Change it to inet_interfaces = all (or just comment out the line since the default is all) and do a postfix reload.  Then try the port scan again.
