As has often been pointed out, if it's domains you already know something about, you don't need ADSP. ADSP is only the most obvious of assertions that people make about the mail they send. If you don't know the sender, you can't believe the assertions, so they're useless. If you do know the sender, you don't need the assertions, so they're not useful. This is why x= is either useless ot not useful. R's, John _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
