change the helo domain of your mailserver to what it should be, for instance, if your domain is yourdomain.com and your mx record is mail.yourdomain.com then enter mail.yourdomain.com as your helo domain. Some mailservers look up your domain (reverse lookup) and will mismatch your inforamtion, consider its not from the right place and reject the connection. What mailserver are you using?

as well as jjmck's there is a registry key which you can set which sends a copy of the FQDN along with the message which prevents the requirement for the RDNS lookup.

Need to know the version of email your exchange to give correct reg key.

Looks like SPRINT had screwed up the reverse DNS and we were not being properly ID'd on RDNS lookup. Much better now, thanks.
