please show full log lines (you can hide private infos, but do so consistently). do not interpret logs and error messages (I doubt any MTA says "that the other server returned"). > I do not send bounces. I reject them like the above. > it actually looks like you do send bounces. if your postfix relays mail to an internal server, you must configure postfix to reject unknown recipients instead of accepting them and then bouncing. As I already said, show logs and 'postconf -n' for help. > sooo > It's a bad idea to mess with the rejection message. Thanks again. > > Gary
