How Do I Remove an SMTP address template from newly converted email policies

We have nearly completed an intra-organization migration from Exchange 2003 to Exchange 2007.
         In Exchange 2003, I created 3 email address policies, implemented via custom recipients assignments. In all a total of 4 email address policies have been imported into my Exchange 2007 environment, and I used the Set-EmailAddressPolicy "Policy # 1-4" -IncludeRecipients AllRecipients to update all 4 email address policies. (My accepted domains have also imported with no problem).
         However, when opening up Organization Configuration\Hub Transport, I get
                           " Microsoft Exchange Warning  Warning: There are recipient policy object(s) that do not contain e-mail address properties. Those policies are not shown unless you use the parameter "IncludeMailboxSettingOnlyPolicy" in the Get-EmailAddressPolicy command."
          When I run Get-EmailAddressPolicy -IncludeMailboxSettingOnlyPolicy, I receive the following message: "WARNING: The SMTP address template '' is invalid because it references a domain that is not an accepted domain."
          This is an old routing proxy that I used some years ago when completing an inter-organizational migration from Exchange 5.5 to Exchange 2000. I assume that this proxy ('' ) is still buried deep in ADS.
           Does anyone know what command(s) that I can use in EMS to get rid of this old proxy (and hence the error)?

Thanks in advance.....

Using ADSIEDIT navigate to recipient policy -> Your problematic email address policy -> go to its properties -> gatewayproxy attribute -> remove what you want :)
