SYMPTOMS
========

If you send an e-mail message to an invalid domain name that contains a trailing
space (for example, SMTP:joeuser@invaliddomain.com ), a non-delivery report
(NDR) that indicates an invalid host is generated as expected. But if you click
Send Again, you do not receive an additional NDR message. Instead, the Internet
Mail Service logs the following event 4120 error message, and moves the message
into the Archive folder:

  Event Type: Error
  Event Source: MSExchangeIMC
  Event Category: Internal Processing
  Event ID: 4120
  Date: 1/11/2000
  Time: 3:17:57 PM
  User: N/A
  Computer: BACON610
  Description:
  In the process of creating a notification of delivery failure to the sender of
  a message, an error occurred causing the notification to be aborted. The
  sender is not informed that his original message failed to be delivered.

==========
