For what it's worth, the only way to create a convincing fake routing history in a message's headers is to find an open relay that doesn't properly stamp mail it receives. There are a very few SMTP servers which will receive and forward a piece of mail without adding a "Received:" line that says where they got it from. Thankfully these machines are almost all gone since they have been brutally punished by spammers pumping messages through them. They're also listed on blacklists, so many people (myself included) wouldn't see messages that came through them. miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
