Does anyone have a step by step howto for newbies on how to make Mailman
work with Exim4 on an Debian Etch system? The readme file says only this:

###
For users of exim: if you want to use the /etc/aliases file for mailman
aliases, you'll need to specify a user=list line or something like that
in the system_aliases director.
###

I don't understand what that means.
