In the face of intentional unresponsiveness: blacklisting. Start contacting Yahoo.com subscribers and explain the situation to these users, and inform the users that, for the time being: yahoo.com e-mail addresses can no longer participate in the mailing lists, because of Yahoo's new policy: And make some suggestions of good alternatives to using Yahoo mail. Then use mail filters to block messages to mailing list addresses with From: header yahoo.com (which cause the problem), next suspend subscriptions for @yahoo.com users, and configure mailing list software so that new @yahoo.com based e-mail addresses cannot subscribe or post to the lists. -- -JH
