Apart the a real problem with default configuration in mm.cfg that can 
get ouf of sync with list configurations, there are two different 
answers sofar:
- a A rather than a CNAME is needed
- a MX entry is needed

Even if none of them worked for me sofar, both of them requires quite 
important modifications (DNS changes) for something that was just 
cosmetic (differencing real users adresses from list adresses), so I 
prefered to revert to original situation (@zarb.org for everything).

However, it is quite interesting actually that I got different answers 
to this question, so it seems to be quite a complex issue...
