How would having a local MTA change the behavior in the face of a 
duplicate message?

I've seen symptoms of duplicate messages where multiple servers up 
stream are the source of duplication.

Are you implying that local MTA alters this behavior?  Or that it 
provides additional tracing / diagnostic information?

I'm not aware of Mailman having any Message-ID deduplication 
functionality.  Nor have I really seen it as a need.
