Most sites don't like to bounce messages that they've previously accepted, so that means that the spam gets held for moderation, which creates a lot of work for list owners. If list bound mail can be rejected by the MTA at SMTP time, that would save a lot of work for list owners.

Sorry, haven't been following along...

I discussed this several months back on the main list.
https://mail.python.org/pipermail/mailman-users/2013-August/075523.html

Basically I hacked a copy of find_member into scripts/check_subscriber:
   (http://paste.debian.net/hidden/c36ff81c/ )

check_subscriber is called by multiple postfix tcp_tables  (one per
list post addr in master.cf), such that incoming emails are checked
against the membership list, and smtp rejected if not subscribed.
Let me know if you want more details.
