The reason why SPF tanked, was exactly that there are many real case scenarios where you cannot fix that bill. SPF is/was used, unsuccesfully as it is clear at this point, to block SPAM. That was the whole point of it. Reject emails based on forged/fake return address. Besides, every anti-SPAM solution that in order to be successful, expect that all the SMTP servers in the world change something, is doomed from day 1. - Davide _______________________________________________ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail
