There is an alternative in between an open list and a subscribed list,
that I quite like. I am intending to use this at out company, when I
find the time :( 

http://software.libertine.org/tmda/ is Tagged Message Delivery Agent.
The gist is that the first time you send email to the receiveing SMTP
server is generates a request, which it sends to you, asking if you are
really sure you wish to submit this email to the server. The sender then
has to reply including a tag.

Is it viable to implement this on lists.debian.org?
