Reply to "LIST" and NOT to sender?!

[Marti <marti @ hello-again . com>]

Hi there,

I've read the configfile about 10 times now, but still haven't found the right
setting ... (I'm starting to feel real dumb now.. ;))

When people reply to any message from the list, the reply doesn't go to the
list but to the person who's mail you're replying to. This confuses many
people. How can I get Majordomo to change the sender so that hitting 'reply'
will actually send a message to the list?

Thanks!!!
