Hi All,

I have setup and installed an in house mail server using iRedMail 0.8.6. Now I am trying to get another server which is hosting an application to relay mail through the iRedMail server. The application using is using sendmail which is configured to use the iRedMail server as the SMART_HOST. However I keep getting Relay access denied errors. I've played with the postfix configuration a little bit with no luck. Can someone point me in the right direction? Is there something is postfix config that needs to be set to allow it to be used as a relay that I'm just missing.

Output from the app server with confidential information X'd out.
