Hi Derrick,

Tony is right, LDAP probably is the most elegant way of doing this,
however if you are running Exchange 2003 you can get it to do recipient
verification against each of your servers in turn until you find a match
and accept the message or dont find a match and then fail/drop the message.

As I said this is not as elegant as LDAP lookups but it is simpler to
implement if you get scared by lots of curly braces like I do.

Thanks

How to enable a recipient filter in Exchange 2003
=================================================

This information was originally provided by David S. Madole

1. Open Exchange System Manager.
2. Open Global Settings, right-click on Message Delivery, choose
Properties.
3. Choose the Recipient Filtering tab.

Enable the recipient filter on the SMTP protocol binding that accepts
mail from the Internet:

1. Navigate to the SMTP Virtual Server that listens on the Internet
(repeat all of these steps if you have more than one).
2. Right-click on the SMTP Virtual Server, choose Properties.
3. On the General tab (already open), click the Advanced... button next
to IP address.
4. Choose the IP/port binding that corresponds to the one that listens
on
the Internet. Click the Edit... button.
5. Click the check box next to Apply Recipient Filter.
6. Click OK to close.
