Seems like your Exchange server IP address or your domain is on a blocked list.  Go to http://mxtoolbox.com/blacklists.aspx and verify if that is the case or not.

Check that you are sending from the IP that is listed for your MX domain.

ie. your domain (Xxx.com) mail MX shows IP 11.22.33.44
Send out using this IPm - so that recipient systems can verify your sending IP and domain are a match.
