SYMPTOMS

When you try to use a recipient filter in Microsoft Exchange Server 2003, the recipient filter may not work as expected. This symptom occurs if you use Microsoft Solution for Hosted Messaging and Collaboration (HMC) version 3.5. Additionally, you may receive unwanted e-mail messages in this situation.

CAUSE

This problem occurs because HMC uses the Smtpdomx.dll event sink to filter recipients instead of using the Active Directory directory service. The Smtpdomx.dll event sink uses the Domains.dat file to filter recipients. Recipient filtering does not work when the HMC event sink is used because recipient filtering looks up domains in Active Directory. HMC does not keep a list of domains in Active Directory.

How to enable the hotfix

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

After you apply this hotfix, you must modify the registry to enable the hotfix functionality. By default, the hotfix functionality is disabled. The registry setting is loaded when the DLL initializes. To enable the hotfix functionality, follow these steps:

  1. Click Start, click Run, type regedit, and then click OK.
  2. Expand the following registry subkey:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeTransport\Parameters

  3. Right-click Parameters, point to New, and then click DWORD Value.
  4. Type CheckAllRecipients, and then press ENTER to name the new value.
  5. Right-click CheckAllRecipients, and then click Modify.
  6. In the Value data box, type 1, and then click OK.

The relay scenario must be supported by an SMTP virtual server that is not configured to use a recipient policy. Additionally, this registry fix must be used with the Smtpdomx.dll event sink in a hosting environment. After you enable this hotfix and configure an SMTP virtual server, you cannot use that SMTP virtual server for relay. You must create another SMTP virtual server to support relay.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
