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

NAME

       pmdapostfix - Postfix performance metrics domain agent (PMDA)

DESCRIPTION

       pmdapostfix is a Performance Metrics Domain Agent (PMDA) which exports mail queue sizes as reported by qshape(1), as well as aggregate
       statistics collected from mail.log.

INSTALLATION

	   # cd $PCP_PMDAS_DIR/postfix
	   # ./Install

       If you want to undo the installation, do the following as root:

	   # cd $PCP_PMDAS_DIR/postfix
	   # ./Remove

       pmdapostfix is launched by pmcd(1) and should never be executed directly.  The Install and Remove scripts notify pmcd(1) when the agent is
       installed or removed.
