Re:Not sure this is news (Score 1)

I whould do it so; - Put all the people in a mailman mailinglist. - make it so that all posting must be approved by the list admin So when you, or an other person send an message to all your customers (or whatever) it must be approved. You have an "un-send" option this way. Also so you can make it impossible for the receivers of the message to reply to all ( if set the settings of the list correct offcource)
