[Mailman-Users] No address associated with nodename?

[Andrew McLaughlin]

Here's a toughy. Anyone else see this?

I have Mailman installed on Panther with Postfix. Before this weekend, 
it all worked great. I got a new hard drive and reinstalled everything 
anew. I thought I had all my setting right, but maybe I missed 
something? Here's a dump from my log:

Can anyone point me?

Thanks,
