SMTP message failure warning - BadMail messages general failure

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool queries the Win32_PerfRawData_SMTPSVC_SMTPServer Microsoft Windows® Management Instrumentation (WMI) class to determine the value for the BadmailedMessagesGeneralFailure key. The value of this key represents the number of messages sent to the Badmail directory for reasons not associated with a specific counter. The Badmail directory is used to store undeliverable messages. For information about some of the other Badmail WMI counters, see the following Exchange Server Analyzer articles:

There are counters that increment when a message is sent to the Badmail directory for other reasons, as well, including a bad pickup file, no recipients, and triggered via event.

The Exchange Server Analyzer also queries the Win32_PerfRawData_PerfOS_System WMI key to determine the value for SystemUpTime.

If the Exchange Server Analyzer determines the value for the SystemUpTime key is greater than 0 and that the result of the value for BadmailedMessagesGeneralFailure divided by the value for SystemUpTime is greater than 1000, a warning is displayed.

This warning indicates that an average of 1,000 or more messages per day are marked as non-deliverable and stored in the Badmail directory. Messages in the Badmail directory must be manually deleted. It is recommended that review and deletion of messages in the Badmail directory be part of regular Exchange Server maintenance. Allowing the Badmail directory to grow without restrictions could consume all available disk space, and in turn cause Exchange databases to dismount.

  1. Examine the messages in the Badmail directory to determine whether the source of the message is internal or external. Messages in the Badmail directory are stored in ASCII format, and can be opened and viewed in Notepad or another text editor.

    • If the messages appear to be generated internally, you can examine the message headers to determine their origin.

    • If the messages appear to be generated externally, it may indicate that your Exchange Server is being used as a mail relay.

For information about how to control and configure relay options, see Microsoft Knowledge Base article 313395, How To Examine Relay Restrictions for Anonymous SMTP Connections and Filter Unsolicited E-mail Messages in Exchange 2000 Server.
