SYMPTOMS

You add a new domain to the accepted domain list in a Microsoft Exchange Server 2007 organization. When you send an e-mail message to this new accepted domain, you may receive the following NDR message:
550 5.7.1 Unable to relay for user@domain.com
The NDR message indicates that the new accepted domain does not work.

Additionally, the following event is logged in the Application event log:


Event Source: MSExchange ADAccess
Event ID: 2803
Description:
Process %1 (PID=%2). The Active Directory notification callback for %3 has timed out. Exchange Active Directory Provider will no longer deliver configuration change notifications to the component.

CAUSE

This problem occurs because the accepted domain list is not updated after you add the new domain. After you add the domain, the Active Directory directory service sends a notification to the Exchange Transport component to update the accepted domain list. Sometimes, this notification is delayed and this notification times out. Therefore the accepted domain list is never updated. Additionally, laternotifications are not processed.

RESOLUTION

To resolve this problem, install the following update rollup:
