Event Information According to Microsoft :
Cause :
This Warning event indicates that the transport process detected a message that could harm a Microsoft® Exchange environment. That message was moved to the poison message queue.
The poison message queue is a persistent queue that isolates messages that are detected as potentially fatal to a computer that is running Exchange Server 2007. This queue is typically empty. If no such messages exist in the poison message queue, the queue does not appear in the queue viewing interfaces.
Resolution:
No user action is required. However, we recommend that you contact Microsoft Product Support to report the potentially harmful message that Exchange detected.
