The suggestions from the link: Suggestions: * Suspend posting permission of all yahoo.com addresses, to limit damage * Tell Yahoo users to get a new mail account somewhere else, pronto, if they want to continue using mailing lists * If you know people at Yahoo, ask if perhaps this wasn't such a good idea does also not sound really good. Not sure if yahoo will fix this, otherwise we need to upgrade the mailman (as brought up from Daniel in another mail) or remove them. Both options are not really good. @Daniel - I have sended the unsubscribed members from this morning to you over private mail. About 1/3 are not from yahoo, maybe you can bulk subscribe them again.
