I don't think you want to use AFD for that purpose. The AFD list is not
tied to any particular list and as such if you delete a subscriber from
your list he doesn't get deleted from the AFD list.
DISTRIBUTE doesn't let you pick the recipients of a list for mail
delivery, unfortunately. The rationale is that if you want to send mail
to a list, you want the message actually sent to the list so that all the
access control verifications are made and the message ends up in the
notebook. The list may not be open for public review, it may have a
moderator, etc.
