SMTP Error

[spruce009]

We recently removed an Exchange 5.5 server leaving two Exchange 2000 servers (now in native mode). We are behind a firewall, and do not send out email over the internet, but we do send emails to other agencies in the complex that we allow communications with. After removing the 5.5 server, emails to the outside agencies fail to work, but inbound emails are coming through. We are getting the following error when sending......

Your message did not reach some or all of the intended recipients.

Subject: xyz
Sent: Date

The following recipient(s) could not be reached:

'xyz@domain.com' on 3/9/2005 11:49AM
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<xyz.domain.org #5.7.1 smtp;501 5.7.1 This system is not configured to relay mail from <name@domain.com> to <name@domain.com> for 192.168.1.1>

Any help would be greatly appreciated. We have removed and configured a new SMTP connector, but no luck.

Did you setup your SMTP protocol to allow all authenticated?

I'm Certifiable, not certified.
It just means my answers are from experience, not a book.

Yes...another piece of the puzzle is that this is on a clustered server. The SMTP Virtual server in IIS is not an option.
