Do you see why it would not work?
How do you know it's not working? From what you say so far, you know the post was delivered to Mailman, and you know the rejection notification was not delivered to the poster. It's possible that Mailman did send the notification, but it got hung up at one of the MTAs in between.
If Mailman is working as it should, there should be entries in Mailman's mailman.log showing the moderation action and in smtp.log showing the outgoing mail. There should also be entries in the outgoing MTA's log, and possibly further MTAs downstream.
