If you want to try making your suggested change then (for MM 2.1.2) look to 
line 342 of Mailman/Handlers/SMTPDirect.py in function bulkdeliver() and 
change:

     msg['Sender'] = envsender

to read:

     msg['Sender'] = mlist.GetListEmail()

Do not forget that indentation is syntactically significant in Python!

This change should lead to the SMTP envelope having the bounce alias on it 
while the Sender is just the list alias. Do not blame me if inappropriate 
stuff starts getting posted to the list because of the change and do let us 
know how you get on with the change.
