Re: 550 5.7.1 access denied Email Problem

We do not have Sender Filtering configured on this box. We also don't
have any Recipient or Connection Filtering setup. What else could it
be?

domain listed? If so, you'll have to remove it in order for this to work,
or you'll have to configure the HR system to send as a different address.

Scenario:
Our HR has a web application outsourced. This application needs to be
able to send email into our Exchange from our users Exchange address to
other Exchange users on our server. But the email is not originating
from our mail servers - its originating from the vendor's mail server.
Our exchange is giving the following NDR:

You do not have permission to send to this recipient. For assistance,
contact your system administrator.
<smtp.vendordomain.com #5.7.1 smtp;550 5.7.1 <user@xxxxxxxxxxxxx>...
Access denied>

How can I configure our Exchange server to allow email from this
specific server to be spoofed and delivered to our users?

We have Autentication enabled - anonymous access, basic and integrated
windows. Relaying is restricted to listed systems - none currently
named. Connections are not restricted.

Any help greatly appreciated...
