Please help with Postfix config issue - How to allow remote Exchange server to relay to my postfix

Hi guys

One of our clients have a problem with sending email to a certain domain. No matter what we try, the mails just dont get delivered.

What I did then, is created a new connector on their Exchange server, pointing all mail sent to their client at "domain1" to relay to our Postfix mail server that we use. Mail from us to "domain1" works fine.

I have given their Exchange server access to our relay in postfix. I dont get any RELAY access denied errors when testing email.

The error I get in our postfix maillog when I send a email to user@domain1.com from our client Exchange is:

Code:
 
Feb 26 11:53:03 ourpostfixserver postfix/local[7354]: 6B307A4D822: to=user@domain1.com, relay=local, delay=1, status=bounced (unknown user: "user")

I know I probably missed some config in postfix somewhere...

Would appreciate any suggestions.

Thanks! Smilie
