I am sort of suspecting postfix as /var/log/maillog is not being written to.
That's bad. So try stopping and starting postfix (after stopping check with "ps auxwww|fgrep post" to see if there's anything left!!!)
and have a look at /var/log/maillog while doing this.
While I don't object at all to the conversation, this is venturing outside of mailman and into system management (DNS function, are the file systems full, which processes are running, etc).
