The folks that are willing to go through piles of spam to find the non-spam emails from non-subscribers do us a tremedous service, since it allows cross-postings across WGs (which is important to help with coordination of the IETF work IMHO), without subjecting the rest of us to spam. Requiring those folks to take the initiative to add folks to the mailing list has the issues others have pointed out (about guessing the intent) and is also putting the burden on folks I think we should reward for filtering spam. If folks need to post all the time from a different address than their subscription address *they* should take the step to get that posting address added to the approved posters list. Erik
