So you have users in your domain who are sending to hotmail and AOL accounts and getting NDR's?
Can you post the full NDR's please?

I can send fine with my email, but I was forwarded some of the bounced emails with the following message in the header: 554 Invalid data in message Can anyone help point me in a good direction to try to figure out what the heck is happening?
