Thanks, the possible solutions found so far:

1) upgrade mailman to 2.1.16 which has an option to replace From header 
with the address of the mailing list. The really big inconvenient is 
that all emails will be handled like this, losing the sender 
information, no matter is from yahoo/hotmail or not. Another 
inconvenient is that it might require manual installation, since 2.1.16 
is not packaged on old debian stable, adding overhead in maintenance ... 
unless some good sysadmin around here provides some backports

2) ask those people with yahoo/hotmail/... to use different email provider

Combined, yahoo+hotmail account for a bit more than 200 addresses on 

What people here prefer? Any other solution?
