If the Microsoft Exchange Server Internet Mail Service has Message Delivery configured for Forward all messages to host on the Connections tab and Diagnostics Logging is set to any level other than None for the SMTP Interface Events, you will receive the following event in the Event Viewer Application Log:

Event ID: 2003
Source: MSExchangeIMC
Category: SMTP Interface Events
Description: A new TCP/IP connection has been made to host x.x.x.x (for
Logfile: L0000000.LOG

All messages sent out through the Internet Mail Service show the same domain name in the description.

If SMTP Protocol Log is also turned on, the event listed above will display the name of the log file where this SMTP transaction was recorded. This can be found in the \exchsrvr\imcdata\log folder. If SMTP Protocol Log is set to None the value for Logfile in this event will display None.


Microsoft has confirmed that this is a problem in Microsoft Exchange Server 5.5.


The domain that is displayed in each of these Success Audit events will remain the same until the Internet Mail Service is stopped and restarted. At that point the domain name for the first piece of mail that is forwarded to the specified host on the Connections tab will be used for each new Success Audit event 2003. This process will continue each time the Internet Mail Service is restarted. This will not cause problems with mail flow and can be ignored. The IP address portion of the event description should be correct for the host that is responsible for relaying the outbound SMTP mail.
