We have a Unix server that sends SMTP internet messages via aqn Exchange 5.5 server. The mesages are system notifications sent to a phone company for SMS messaging. The Unix server and the Exchange server are both in the same domain (xyz.com.au). The messages are being forwarded by the Exchange server via a distribution list. The problem is that the Unix server is adding its hostname to the sender address (server.xyz.com.au), and the destination is required to verify the sender address before sending the SMS message, but it cant verify server.xyz.com.au address.
Question is, how do we get the Exchange server to strip the hostname from the sender address.
