I think your questions and available answers are written so very few could follow what you mean. Why don't you rewrite them in simple English? Just outlaw spam and thats all there is to it. A "no spam" list is not the answer. What if I change my email address? Then the no spam list is invalid. Just have the ISP to reject any email from someone not not in the users address book. AOL has this feature and maybe some others. Why make it so complicated? Wendell Deen
