Hotfix information

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 your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

After you install the hotfix that is described in this section, you must create the DropBadMailIfNotNDR registry entry. If the DropBadMailIfNotNDR value is set to 1, Exchange 2003 routes the NDR to the Exchange.Bad folder of the Lotus Notes server. Depending on the number of NDRs and the size of the NDRs, the hard disk volume of the Lotus Notes server may be affected. You must regularly examine the Exchange.Bad folder and the hard disk volume.

To create and to enable the DropBadMailIfNotNDR registry entry, follow these steps:

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then select the following registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LME-NOTES\Parameters\
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type DropBadMailIfNotNDR, and then press ENTER.
5. Right-click DropBadMailIfNotNDR, and then click Modify.
6. In the Edit DWORD Value dialog box, click Decimal, type 1 in the Value data box, and then click OK.
7. Quit Registry Editor.
