One of the lists to which I subscribe has chosen to put the list as the secondary element and the individual posters as the primary. That’s fine, but the side effect of this is that when I reply to a message, it goes to the poster, and not to the list. I don’t like the behaviour, but the list admins are plainly happy with it. I resigned myself to replying-to-all for the purposes of that list, until I saw this procmail recipe:

:0:
* ^(From|To|Cc).*\@listdomain.eg
  {
    :0hf
    | /usr/bin/formail -A "Reply-To: listaddress@listdomain.eg"
    :0
    folderforlistmail
  }

I much prefer to hack the client-side then try to change policy on the server-side. I am almost universally less resistant to change than any organization.
