Explanation

This event indicates that the Microsoft Exchange Transport service SMTP Receive component can't process an SMTP message submission from a particular user.

The Microsoft Exchange Transport service controls the sending and receiving of messages in Microsoft Exchange Server 2010. The Exchange 2010 transport pipeline uses the SMTP Receive component to validate the message content before the message can be submitted to the Submission queue. The SMTP Receive component applies a series of receive events and, if configured, antivirus and anti-spam events to validate the message. Additionally, the SMTP Receive component contacts the Active Directory directory service to validate users who submit messages for delivery. This event represents a general catch-all event for issues that occur but that do not trigger other events.

For example, this event could be logged if the SMTP Receive component can't contact Active Directory to perform an authentication check before accepting a message. For more information, see the following topics:
