At a quick glance it doesn't look like it would be all too terribly 
difficult to change.   When I was using Mhonarc for the archives on 
one of my lists (before moving to Mailman last spring), I had a 
script that would change "user at domain.com" to" user at ...".  If I 
recall, it simply used a regex that looked for characters followed by 
an @ followed by more characters.  It then replaced everything from 
the @ to the next space with "...".

It appears that the code which does the obfuscation is in 
($prefix)/Mailman/Mailman/Archiver/HyperArch.py between lines 280 and 
290 in 2.1.11. (I'm sure someone will correct me if that's wrong info)
