The Microsoft® Exchange Server Analyzer Tool sends a test message from the Exchange server to the Postmaster account or a user-defined account for the Simple Mail Transfer Protocol (SMTP) domain and then scans the message tracking logs of the server to determine whether there were issues with the delivery of the test message.
As a part of this scan, the Exchange Server Analyzer queries the EntryType property for the Exchange_MessageTrackingEntry Microsoft Windows® Management Instrumentation (WMI) class under the root\MicrosoftExchangeV2 namespace to determine what caused the message tracking log entry.
If the Exchange Server Analyzer finds a value of 1021 for the EntryType property, the Exchange Server Analyzer displays a warning.
This warning indicates that the test message was sent to the Badmail directory for the Exchange server and there is a problem with the Simple Mail Transfer Protocol (SMTP) configuration for the server.
A message is entered into the Badmail directory for one of the following reasons:
- It cannot be delivered.
- The maximum number of retries has been exceeded.
- It cannot be returned to the sender as undeliverable.
