Put the person under moderation until they fix the problem. You can leave them on moderated status unless or until they let you know the problem has been resolved. Don't put the entire list on moderation because one person got hacked. However: when staff does a global removal -- and the person doesn't know why (maybe they don't get the email staff sends out) and resubs...they will no longer be moderated unless you set them up as moderated after they resub.

One of my subscribers evidently caught a virus, and sent a post with no subject, and only a URL in the body. That was particularly bad because that subscriber was also on almost 50 other Lists, and Gerhardt had to do a global removal of the subscriber. I saw the same thing over the weekend on a List to which I subscribe. It is a growing problem, and we are helpless to prevent it under the instructions. I have been able to prevent this in my Lists that are gatewayed, because I have the gateways moderated. Everything that is going to the gatewayed Lists is sent to me first for approval. I want to do the same thing on my other Lists. Reading the Mailman Instructions, I see two ways to this: put the Lists on Emergency Moderation, or place each subscriber on Moderation. However, the Instructions say that; "It is recommended that individual moderation, like emergency moderation, will be a temporary setting." Is this cast in stone, and will I get into trouble if I make the moderation permanent? Is there another way I am missing? Carl Hommel
