Postfix is listening on 127.0.0.1:25 is it ok? or should listen on 0.0.0.0:25??
Listening on the loopback address is sufficient if you just want to send mail. If you want Postfix to receive non-local mail to be delivered to Mailman, you need to listen on an internet connected interface.
If you put
inet_interfaces = all
in main.cf replacing any other inet_interfaces setting, that should do it.
