SYMPTOMS
When you configure a transport event sink to prevent the posting of a message to a newsgroup folder, the blocked newsgroup posting (.nws) is still written to the hard disk.



CAUSE
This problem may occur when you configure an event sink that implements the OnPost event. It occurs because the .nws file is already written to the hard disk when the OnPost event handler is called.

When the posting is canceled, the users cannot access the message item; however, the .nws file is not deleted from the file system on the computer.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
When you configure an event sink that implements the OnPost event, and you change the NNTPProcessing field in the envelope to a value of 0 (zero) to prevent the posting of messages to a newsgroup public folder, Network News Transport Protocol (NNTP) clients receive a notification. The notification indicates that their posting has been blocked after they try to post a message to the folder, as you expect.

However, when you view the contents of the folder that the client tried to post the message to, you notice that the message has been written to the hard disk as a news (.nws) file. After you install this update, filtered newsgroup postings do not remain on the hard disk.
