Diagnostic-Code: X-Postfix; mail for 10.42.34.100 loops back to myself

Since updating our Mac OS X Server software, our outgoing emails have ceased and we receive the error shown above. We are running Mac OS X Server 10.3.9 and Entourage as our cleints. The mail seams to be received ok. Does anyone know how I can fix this???

G4 500, Mac OS X (10.3.9)

You receive this error when sending mail to outside domains or your own domain.

To help, we need to see your configuration. Post the exact results (do not modify, do not remove domain name, modify IP addresses, etc) of the following command in Terminal:

postconf -n
