I can't seem to figure out how to allow out-going messages.  It seems that incoming is working.

Thanks in advance!

Run your domain through this MX record test utility and post the results (or any that seem relevant).
The invalid HELO sounds like your Exchange server is announcing its name to the receiving server with an invalid name, probably its local AD name. You will need to go into the Exchange System Manager program, then into the "Default SMTP Virtual Server" properties. Go to the Delivery tab at the top, then hit the Advanced button. There is an entry blank for the Fully Qualified Domain Name. It may be set to something like exchsvr.domain.local. It needs to be set to a valid name on the Internet. Probably the same thing as your MX record in DNS.

Let us know if you need more details.

Upon further investigation, the emails are sitting at the SmallBusiness SMTP connector.  They are stuck in Retry status and do not seem to unfreeze....Any thoughts?
