Question : SMTP Relay problems

I'm having an SMTP relay problem and I'm at I'm about at my wits end.  This is a fairly simple (and small) setup.  All the Exchange 2007 roles are on one box.  There is a firewall, but I've blown the necessary ports open, and as you can see by the following exchange 2007 server log the connection is being made.  I have tried several things including now using IP addys instead of domain names, and changing the timeout from 10 to 15 minutes.  Please note I've filtered the IP addy and e-mail addy on this log:
