Post the rejected transaction(s) from your logs please. It's likely they are rejecting your mail due to the presence of "ppp" in the rDNS name, which typically indicates consumer broadband IP space. I block smtp connections based on such rDNS names myself, as do many admins. If you are sending mail from dynamic IP consumer space, I recommend reading this document: http://www.hardwarefreak.com/postfix-adsl-relay-config.txt -- Stan
