There were multiple spam with email addresses of yahoo.com, yahoo.co.jp, and hotmail.com. In all cases they were sent from IP address totally unrelated to those domains and all were prevented from entering the system. This one particular client doesn't use whitelists and they don't experience any delays in delivery from those domains simply because they have been populated in the DB and due to the frequency they connect those records don't expire. Oh, FWIW, there is no such thing as an "outbound MX host". :-) -- Your files are now being encrypted and thrown into the bit bucket. EOF 葛斯克 愛德華 / 台北市八德路四段
