I hope you don't take offence when I say that your messages come across as rather hostile. Unfortunately when dealing with a 3rd party it's not always possible to ensure RFC compliance so on some occasions exceptions have to be made for the sake of getting things working. Perhaps "incorrectly configured" was the wrong phrase to use. It's not that there is anything inherently wrong with the smtp.enta.net server, rather it wasn't designed to do what I'm asking of it. I'm going to setup reverse DNS for the IP of this connection and send out directly from the clients Exchange server. Thanks for your input. James
