Also, how do I specify my exchange server authorise to relay outbound mail?

Answer : POSTFIX Bounce message

Hi,

You have this in your logs:


Aug 13 20:24:22 corpmail postfix/smtp[15626]: 0CD8C3E70043: to=om.au>, relay=none, delay=2.1, delays=2.1/0.01/0.01/0, dsn=5.4.6, status=bounced (mail for uwc.com.au loops back to myself)
Aug 13 20:24:22 corpmail postfix/cleanup[15620]: 1DDA53E70045: message-id=<20090813102422.1DDA53E70045@corpmail.uwc.com.au>
Aug 13 20:24:22 corpmail postfix/bounce[15622]: 0CD8C3E70043: sender non-delivery notification: 1DDA53E70045

It means that uwc.com.au DNS MX points to your host so that mail for the domain gets deleivered to your host. But your postfix does not have uwc.com.au in mydestination section.

So it can not deliver and loops the mail. Also you need to eidt tranprt virtual etc to deliver it to an inside server..

Cheers,
K.
