[plt-scheme] plt-scheme.mbox (help...)

A bit off topic, but I did search Google and Apple for [too-long].

I downloaded plt-scheme.mbox, the email archive, and I can look at it 
as a text file in Emacs.  But I'd rather see the threads.  I tried to 
import the "standard mbox format" file into Mac OS X Mail, but it 
didn't work.  How do other people look at these files?  (Convert to 
Emacs RMAIL format?)

Thanks,
Geoffrey
