Good point. So messages that get emailed to the mailing list are filtered before they get sent out to the Usenet group. And messages from the Usenet group can be filtered by the mailing list admins before they are copied back to the mailing list. But messages originating on Usenet by definition are visible to all Usenet folk. So to answer the OP's question, messages originating on Usenet cannot be filtered by a mailing list admin before they are visible to other folks on Usenet. -- https://mail.python.org/mailman/listinfo/python-list
