Seems interesting but it will of course break the 'ban list' itself, you
won't be able to ban people. I didn't reply before because I didn't have
time, but this morning I just peeked at the web interface: sender
filters (my web interface is configured in French so that might not be
the exact phrase)

The question I have is what was wrong with "accept_these_nonmembers" in
the first place (since it can take regular expressions it could accept
whole domains) and then allowing only members and those domains in
"accept_these_nonmembers" to post to the list? You have a number of
options on that screen that should already answer your question
("reject_these_nonmembers" "discard_these_nonmembers"
