When you send an encrypted message from Louts Notes to Microsoft Exchange Server 2003 by using Exchange Connector for Lotus Notes, Exchange 2003 does not send a second non-delivery report (NDR) for the encrypted message. Typically, this problem occurs when the auto-forward feature is configured for the Lotus Notes client.
Exchange 2003 cannot parse messages that are encrypted by Lotus Notes. Therefore, Exchange 2003 sends an NDR to the Lotus Notes client. If the auto-forward feature is configured for the Lotus Notes client, the NDR is returned to Exchange 2003. If Exchange 2003 sends a second NDR in response to the returned NDR, a message loop occurs between Exchange 2003 and the Lotus Notes client.
To avoid this message loop, Exchange 2003 does not send a second NDR. However, if Exchange 2003 does not send a second NDR, the encrypted message that generated the first NDR is lost.

Hotfix informationWarning 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:
