how do i put listname in the from: clause of any outgoing messages?

["mr. byte" <mrbyte @ andrews . lv>]

hi

how can i force users to reply to my list, rather than to users who post
messages?  i know there's a reply-to thing, but i would like:

- to put $sender in the reply-to field and put "Posted by: $sender" in the
message body at first line

- put "listname" in the "from:" clause of the message

this would make discussions keep going, otherwise, users always tend to
reply to message authors...

thanks for any help!
