What happens if a dozen of us add a yahoo filter that marks "blabermount at his.domain.com" as spam. i.e. what happens on large mailing lists when a service like yahoo sees a set of messages from a specific user as spam. Then what happens when a handful of users on that list fall into the spam category... at what point does the list server look like a spam source? I have seen one or two junk mail messages in my list folders recently and see a bunch of normal posters end up in my spam folders both on google and on yahoo. -- T o m M i t c h e l l Found me a new hat, now what?
