Trying to send messages from an automatic procedure i receive an NDR
reporting
<SERVER #5.1.0 smtp;550 5.1.0 <Name@xxxxxxxxxxxxxxxxxx> sender
rejected your domain part is not good>
if i use a real smtp address for the sender the message is delivered
succesfully.
What can generate the problem ?
The message is generated from an AS400 server and delivered to an
Exchange server for the relay.
Exchange 2003 sp2 on Windows 2003 sp2
