some disagree but generally leaving the Reply-to and From unchanged (which may 
of course be different) and adding headers like

Precedence: list
List-Id:
List-Unsubscribe:
List-Archive:
List-Post:
List-Help:
List-Subscribe:

is the way to manage a list because:

1/  most clients will use the List-Id header to offer a reply-to-list option

2/ it is considered by many that the problem of accidently sending a private 
reply to a list is much worse than accidently sending a reply intended for the 
list privately.

not sure how this fits with your signing though
