Let me try this again....
 
Overview:
We have one Exchange 2000 server we are trying to replace that is currently 
exposed (public IP - this is bad... we know).
We have just added a new Exchange 2000 server that is on a private IP and 
behind an MS ISA firewall only box.
We have only migrated a couple of email accounts from the old Exchange server 
to the new one for testing and are experiencing problems when sending to those 
accounts.
We can send internally to any email account without problem, as well as send 
mail externally without problem.
We are unable to send mail to any of the users that we migrated to the new 
Exchange server, when we try we get the following error:
 
Your message did not reach some or all of the intended recipients. 

  Subject: FW: Welcome to the ISAserver.org Discussion List

your system administrator.
  <exodus.tmfi.com #5.7.1 smtp;550 5.7.1 Unable to relay for 
test_user@xxxxxxxxxxxxx>
 
ISA configuration:
We have published our Exchange server using the Secure Mail Server publishing 
wizard.
Users are able to access the internet.
Protocol Rules allow for DNS Query and DNS Zone Transfers and SMTP to travel out
IP Packet Filters configured for SMTP inbound and SMTP outboud (individual 
filter entries)
 
Other configuration info:
The Exchange server has a private IP and is configured with DNS services.
The NIC DNS entry points to itself and the DNS service is configured to forward 
to our ISP's DNS server.
The default gate way is the private IP of the ISA box.
The recipient policy used for the user accounts having problems is the default 
for our domain.
 
 
Any ideas why we are having his problem?
 
Thanks - Dave
