SMS messages won't send
communicating back and forth from SDP using Exchange 2010, however when we try to use the SMS feature it fails:
Caused by: com.sun.mail.smtp.SMTPAddressFailedException: 550 5.7.1 Unable to relay
Has anyone run into this before? I suspect it's a configuration with my Exchange server, but I'm not sure what we need to do to enable this.
