SMTP outbound fails Event logs show event 3200, 3267 and 9158

Hello,

I have an Exchange 2003 front end server and 3 Exchange 2003 back end servers.  The Front end server sits in the DMZ and is the only server allowed to send smtp outbound.  SMTP outbound works fine for any Outlook client.  But applications cannot sent an smtp message out and I also can't telnet smtp out.  When I try to telnet, the message says that the mail is
queued for delivery, but it never gets delivered.  I can't see it in the queue. When I tried message tracking, it looks like the mail is delivered to the front end server but never goes anywhere.  I have multiple error messages on the front end server:
