Discussion list domain change problems

Originally, I set up a discussion one a subdomain without realizing there can only be one per domain.

So I used


rather than

(which would have made it more graceful to add new lists)

When I did need to make a few more, I changed the domains. The problem is that during the time of that switch a user sent a message to the old list name, and it still appears waiting for moderation. However, when I try to delete or approve the message, the form submits to the old domain and I get a server not found message.

Is there any way I can moderate the message? The main problem is that I get daily email reminders (which I wouldn’t want to stop for other messages).
